    What is worst amp you have had that worked

    I used it with a tannoy LGM, DIY full range FR125, Mission 752. Eventually assigned it to stereo subs. Replaced with a icepower 700. I didn't dare try it with either of my electrostats. Didn't mean to insult but it really didn't do anything for me. My main amp was a Bryston 4BST at the time which now works really well with the Tannoys. Regards, kffern

    Rotel RB1080. Fortunately I bought it cheap though. Looked nice but it sounded horrible. Dry and non musical. Should have stripped it and fitted a kit amp. Kffern
  3. Item: Toroidy Supreme 1200VA 2 x 65V Transformer (230V) Location: Perth WA Price: 250 plus shipping (negotiable) Item Condition: Used Reason for selling: Replaced with 2000 VA transformer from Toroidy Payment Method: Pickup - Cash, Paypal, COD, will post Extra Info: I got this toroid with an DIY Holton HPA-NVL800 Stereo amp I bought via Stereonet. I used it with my Kings Electrostatics (early pair circa 2009) and it worked beautifully. So good that I reinstalled the crossovers and ran it with the one amp and it sounded better than it ever did DSP bi-amped with a Bryston 4B ST and a Panasonic Pro amp . However, with the 2 ohm load of the Stats, I wasn’t sure if I was getting all that the amp could give, so I bought a 2000 VA Audio grade toroid from Toroidy and replaced it. Saying that, the amp barely got warm even after running all day. It ran absolutely silent as well. Now I can understand what the reviews of the Kings were talking about. I don’t think I gained anything apart from a slight bit of transformer hum but will keep it as I have already gone down that route. If I had an 8 or 4 ohm speaker I would be quite comfortable keeping it. A new 1200 VA Supreme transformer will cost you over AUD 600. This doesn't include the mounting plate and bolt which I have included. I estimate shipping around $60 to the east. https://sklep.toroidy.pl/en_US/p/TTSAS1200-SUPREME-AUDIO-grade-transformer-TSAS1200VA-voltage-from-55-to-100-V/425 https://www.diyaudio.com/forums/holton-precision-audio/324517-nxl800-amp.html https://www.diyaudio.com/forums/holton-precision-audio/300643-nxl800-amp-build.html ELECTRICAL DISCLAIMER This product has not been manufactured by a qualified individual or company, therefore contains electrical circuits that do not necessarily comply with Australian Standards.

    Bryston 14BST , 4BSST or other?

    I would look at Holton amps. I have an early 4bst driving large electrostats. The Bryston does a good job but the holton (nxl800) is a different class. One of the 300 or 200w models would be a good match for your ribbons. Kffern

    Corian sheet

    Is anyone in Perth interested in going halve on a 600x3000mmx12mm speckled white sheet of Corian? They want $250. I want to make a tt plinth. Thanks, Kffern
  7. Hi Jazzman, Love your builds and posts. I look forward to see how you physically configure the resistor network and get it nice and compact. Saw driedchalk's version which looked good but not sure of values used and configuration. Regards, kffern
  8. pmd with payment confirmation and postal address. Can't wait to plug them onto my old Kingsound Stats... Thanks Kffern
  9. Pmd with my contact details and very keen on buying. Kffern

    DIY Linear Tracking Turntable

    I worked my way up from cheap Chinese stuff to abec 7 steel. One of the guys on the thread insisted that play was required but I don't think so. I didn't throw too much money at it. I did consider the xyz mount as you did but building a good carriage was the problem. I still have dreams of having another go but not enough time at the moment. kffern

    This is interesting now that the roadrunner etc. is no more. A hole in the market it seems. I still have to finish pyramids PS. Kffern Kffern

    DIY Linear Tracking Turntable

    There is a long running but now dead thread on diyaudio on the parallel tracking bearing arm. I tried to have a closer look at the clearaudio version in a KL showroom and it does look like they use some kind of metal carbide material. kffern

    DIY Linear Tracking Turntable

    Your implementation of the arm is impressive. I had the same thing working for quite a while but it was fiddly and I ended up breaking a stylus. When it worked it sounded fabulous. Did you make those aluminium pieces for the arm carriage? They look like cast pieces. If you recycled them can you tell us what they were from? Whats a ZR manual trimmer? Regards, kffern

I've seen these advertised for $20 to $40. 3 are NOS Nagaoka in original sealed box, not sure of the other 2. Pictures:
