  1. The 11-20 series had 27 variants, differing in valve line up, speaker type, circuit variations etc. Which one do you have? There's a bloke in Queensland called David Tipton who repairs and restores these. He has a YouTube channel under the same name. However, in answer to your question the safest way to power up any old mains powered electronics which you suspect might be faulty is to use a dim bulb tester with or without a variac. A simple dim bulb tester is essentially an incandescent 240v light bulb (no LED and CFL bulbs can't be used for this purpose) wired in series with the active lead in the power cable. For a radio of this type a 60W should be suitable. What the bulb does is limit the current flow. On switch on the bulb will glow brightly for a few seconds and slowly dim down to a faint glow if all is basically good. If it stays on brightly it is a good indication that there is a fault in the radio that requires further investigation. Cheers, Alan R.
  2. Love that simplicity. 👍 Cheers, Alan R.
  3. No problemo. My signature doesn't represent the status quo as far as my audio or even my video equipment goes. I haven't updated my signature list as any new entries can't be added to a list as lengthy as my existing list due to the newer limit on the number of character allowed. Unlike most HT setups, my multichannel system doesn't suffer the typical shortcomings of most HT setups which have small rear speakers, a rather dialogue focused centre speaker and a LFE (subwoofer) set up for boom, crashes and explosions you find in a lot of action movies. Rather, my current system in the audio studio is set up for music listening has large full range speakers and a subwoofer set up for music listening with no blending necessary to compensate for the lack of bass in the other 5 channels. IME, most systems set up for rarely play music really well no matter how good the gear is as many users opt for the accentuated bass boom of the sub-woofer (generally cranked on average 15dB too high) for music because they want the floor rattling effects from the explosions in preference to a more natural balance you'd expect from music in a properly mastered multichannel mix. SACD, just like DVD-A, dts-CD and flac multichannel files comes in a various channel multichannel configurations of 2.1, 3.0, 3.1, 4.0, 4.1, 5.0 and 5.1 as you are probably aware. To get the best music sound reproduction from any of these formats you really need a good set up with preference to 5 full range speakers of equal or near quality / tonal balance and a sub woofer set up for music rather than HT. I can see why many people negatively critique multichannel music. Mostly because its played in a HT optimised setup which seems to be tailored for the person's movie watching preferences and the speakers are more than often not placed for the best acoustical performance, but more to "blend in" with the room furniture and the WAF / SAF criteria. Many auto setup HT processors / receivers tend IME to focus on movie sound rather than music resulting in aggressively loud rear speaker levels and the LFE channel ending up way too loud. If someone hasn't heard a pretty good well set up multichannel music system I would sincerely suggest they take the time to do so before relegating the multichannel audio formats to the bin. As for decoding multichannel using a HT receiver or processor. Yes, I have used and still use this method on players that have no multichannel decoding ability. In my case I don't use the power amp section of these receivers. Instead I take the decoded audio at line level from the pre-amp outputs and feed those into separate power amplifiers. In my case the front speakers are Equinox Jupiters with a nominal 2 ohms impedance which most HT receivers and indeed some power amplifiers would have a lot of trouble driving to loud levels. Also the Quad ESL2905 electrostatics can in parts of the frequency spectrum present a bit of a low impedance load to the amplifier, hence I drive both these pairs of speakers independently with a ME-850 HiCap which isn't troubled by even a 0.5 ohm load. Just a side note: Even in a properly set up music optimised configuration some multichannel recordings have IMHO overly loud rear channels. I attribute this to poor mastering. Cheers, Alan R.
  4. Yes, and also from player to player. The average listening level does have a significant impact on hearing perception. Something that Fletcher and Munson demonstrated in 1933, later revised by Robinson and Dadson in 1956, and but yet again in the ISO 226 redefined standard in 2003. Cheers, Alan R.
  5. Fully agree. I have purchased a few SACDs where the SACD layer has been the same as the CD layer. If the original wasn't much chop to begin with encoding it to DSD won't improve it. Cheers, Alan R.
  6. Thank you for your 2 cents worth. I'll treat it with the contempt it deserves. BTW, to go along with your nit picking I'll just like to make it abundantly clear that I have no "HT recievers" in my audio only listening set up. 😜
  7. Softer in what way? Purposefully rolled off top end or simply reduced overall playback level? If the latter, there's thing called the volume control on the amplifier the last time I used my system. 😜 Cheers, Alan R.
  8. I have hundreds of hybrid SACD titles and the same on good ol' Red Book CDs. Can't honestly say the CD layer of SACD / CD hybrid discs are "nobbled" to make the SACD "sound better" when comparing the CD layer with the same on the Red Book CD pressing from the same label . I have easily heard noticeable differences when comparing CDs released on different labels, especially re-releases which I attribute to remastering of the original master recordings rather than the format itself. IMHO it would make no sense in purposefully degrading the CD layer as the whole idea of SACD/CD hybrid discs is to be able to maintain compatibility with CD only players. Besides, the record labels have nothing to gain by purposefully "nobbling" the CD layer. People who had a SACD player in their main music system and a CD player in the car or a smaller system that played CDs only wouldn't buy them in that case. I have ripped a lot of hybrid SACDs and CDs and when comparing the CD layer of the SACD with a Red Book CD in programs like CoolEdit Pro the waveforms are identical, therefore I can pretty much conclude that when comparing apples with apples they are the same. If however if the mastering is different you should hear a difference even on a lesser system. Secondly, no self respecting hi-end manufacturer is going to make a SACD / CD player with purposefully crippled CD playback. If like me, I bet a lot of people might very well already own hundreds if not thousands of Red Book CDs so one might assume that they would want the best possible playback performance of BOTH formats. Having said that, as in the words of @rantan "YMMV" Cheers, Alan R.
  9. As is Kraftwerk's Minimum Maximum. Cheers, Alan R.
  10. Hahahaha. But God gave me 5.1 ears. Sorry, couldn't resist. I'm assuming you are implying that any form of surround sound can't possibly be of audiophile quality? Cheers, Alan R.
  11. Hi Ivan, IME and IMHO what additional benefit you get from SACD vs CD is dependant on the original recording quality. I own several SACD and SACD capable players and there is a difference in sound quality from the cheaper unit compared to the most expensive and dedicated SACD / CD machines. Also it depends on the DACs in the machine if you are using the analogue outputs. IMHO my Sony SCD-XA5400ES sounds pretty good in 2 channel mode through its own internal native DSD DACs, a little less so through the DSD stream via HDMI to a Sony STR-DA6400ES receiver which supports HATS over HDMI, but this is probably more to do with the quality of the DACs in the receiver which first convert DSD to PCM rather than the player Therefore I mainly use the HDMI connection for listening to 5.1 surround SACDs as the player only supports 2 channel stereo playback via the analogue outputs. Back to the issue of sound quality and SACD. If you buy hybrid SACDs from popular music titles or old analogue remasters, other than the possible advantage of a surround mix, you may not be able to fully realise the potential of the format as IMHO you can't make a silk purse from a sow's ear. However you would be getting as good a sound as the original source tape could potentially have provided assuming it was remastered correctly. BTW, there are some awesomely sounding pure DSD titles out there. Anyhow, just my 2c worth. BTW anyone considering abandoning SACD and have titles for sale, message me. Cheers, Alan R.
  12. It's repaired and lives to make another recording again. 👍 No, I didn't leave the screws out. Picture taken during the 24 hour sink test before the board was confirmed as repaired. 😆
  13. I would go with at least 2.5mm thickness based purely on the weight of those transformers unless there is under top plate reinforcing. Copper is a rather soft and malleable metal compared with steel so a thin gauge may sag under the weight of heavy transformers mounted on top with no underside reinforcing / support. Cheers, Alan R.
  14. You could try these two local Yamaha service agents for a belt kit - Complete Electronic Services Pty. Ltd. Shop 2, 660 South Road, Glandore, SA Adept Electronics 5/316 Main North Road Blair Athol, SA Cheers, Alan R.
  15. The persistent hum might be caused by a ground loop or just the high sensitivity of the amplifier input. At the effects sockets, the levels are generally higher so you aren't picking up as much mains 50Hz hum as you would from the more sensitive guitar input. The very loud volume is because the normal input from an electric guitar is just a few millivolts, whereas the output from your music player is more likely to be hundreds of millivolts.
