demoiree Posted September 10, 2020 Author Share Posted September 10, 2020 @R-Y74 thanks for sharing! i'd suggest use the stock tubes to run them in for at least 50 hours , i left mine on for days , and it did further improve the sound. Link to comment Share on other sites More sharing options...
MrBurns84 Posted September 11, 2020 Share Posted September 11, 2020 Well done @R-Y74! The Obbligs are good but i do find them noisy somehow...swapping them over even to the basic Mundorf evo oils dropped the noise down a fair bit. These SGO's will take the pre to another whole level and does help clearly delineate the tube rolling differences. Link to comment Share on other sites More sharing options...

I havent burned in mine for long yet, but the cheaper evo oils have opened up more than the evo supreme oils. Mundorfs do have a house sound. 1 Link to comment Share on other sites More sharing options...

Gordon Macfarlane Posted September 12, 2020 Share Posted September 12, 2020 I like the Jantzen Superior Z caps and they are easily available from Speakerbug here in Australia https://speakerbug.com.au/index.php?route=product/category&path=25_31 1 Link to comment Share on other sites More sharing options...
ferdzb Posted September 15, 2020 Share Posted September 15, 2020 I replaced the Bennic filter caps with Mundorf Supremes. Huge! same length but fatter than the coupling caps. Man, it's a pain feeding the wires into the terminals. I tested a bit and I was greeted by clarity in voice and overall airiness (perhaps it's due to lower noise floor?) and bass is more defined, I didn't expect that. I like it! 1 Link to comment Share on other sites More sharing options...

Haha.. welcome to the club of cap rolling. They're big but well worth it imo. Yes, swapping out the stock caps does yeild a lower noise floor, the tube noise is also lowered by quite a bit. 1 Link to comment Share on other sites More sharing options...
Ram18 Posted September 16, 2020 Share Posted September 16, 2020 Sorry for being ignorant. What does tube noise or floor noise actually mean? I somehow dont experience this noise from my MP. Or maybe I am not looking at the right things. Link to comment Share on other sites More sharing options...

When the system is on, just turn up the volume on the preamp to you normal listening loudness. Without playing any music, sit at your listening position, listen out if you can hear any audible hiss from the speakers. Link to comment Share on other sites More sharing options...

Very useful insight to others tube rolling on the preamp. .... @MrBurns84 You're welcome! I just noticed I forgot to add NOS ECA 12AU7 in that video. FWIW, the ECAs are neutral sounding like the Tungsols but the ECA has no lean sounding bass. Balanced sound in all freq. Good for those who don't want coloration in their systems.

Searching for Magic Posted September 27, 2020 Share Posted September 27, 2020 Hahah.. i think I have unscrew the cover too many times with my unfortunate events with faulty tubes.

Very useful insight to others tube rolling on the preamp. I must echo Mr Burns. Excellent video ferdz. Highly informative and useful for aspiring cap and tube rollers. Learnt a lot from this sharing. Am reassured now the 6h30Pi i bought though its Sovtec tubes do serve well. Thanks for taking time to put this together. Your speakers sing by the way! Now to my next upgrade - switching the rectifier 1 1 Link to comment Share on other sites More sharing options...

Thanks haha , i left mine opened since i started my first set of tubes ... but will cover up once my son starts to walk. @MrBurns84 good to know those tiny bypass caps does something to the sound ! is there any pit falls? im just concerned that DC voltage might escape via the smaller cap. 1 Link to comment Share on other sites More sharing options...
tntman Posted September 27, 2020 Share Posted September 27, 2020 Zero pitfalls at all.. I left my cover off since day one. As for rectifier rolling, I enjoy the Aussie made Philips 5as4 can be bought really cheap.. And my Cossor 53ku.. What rectifiers are you guys using?

Nicee @R-Y74 Was skeptical too at first but it was installed on my MP-P2 phonostage and after listening to them with and without the bypass, it was noticeable. But think of it as icing on the cake and its the absolute last thing to be done. Link to comment Share on other sites More sharing options...
