NIce chamfering work.

Doh! (thank you)

I note that the Hamnett installed SE400 Monoblocks *do* include a separate FE power supply, although there's no obvious regulation. https://www.ebay.co.uk/itm/295745909733?mkcid=1&mkrid=710-53481-19255-0&siteid=0&campid=5338728743&customid=&toolid=10001&mkevt=1

Yes! This is fundamentally true of all solvent based cleaning processes. Otherwise you're simply dissolving the <dirt>, then letting the solvent evaporate, re-depositing the <dirt>.

Thank you. That's majestically unhelpful.

If you have a link to an article (or a few articles) on those ideas, I'd be every-so-grateful! Do they mainly apply to low current "precision" PSUs (streamers, amplifier front end), high current PSUs (power amplifier driver circuits), low-voltage (transistor) or high voltage (valve). So does...

Could you expand/explain this please? It sounds ... really helpful.

Yebbut the old links only have a thread number, not the title😢

Current thread/post links look like this: pinkfishmedia.net/forum/threads/avondale-asr-z-shunt-psu.290367 The URL includes the thread title as well as the number. Old ones look like this, just the number www.pinkfishmedia.net/forum/showthread.php?t=29501 Is there a way to make the old form...

No.

I think he meant the meter.

This is the amplifier board for 1 channel of the Sugden. The highlighted components are the equivalent of the mini6/VBE pair used in a Voyager style Avondale amplifier. :D Sugden Au51 Front end PSU by plybench, on Flickr Oh, forgot - the diodes of the bridge rect are on the PSU board (bottom...

Herewith the front end PSU (bridge rect is not on the PCB) for my Sugden Au51p. As far as I can tell the equivalent output stage PSU is a 10,000uF capacitor. EDIT: It may be of interest that the datasheet for the pass transistor shows an absolute maximum collector power rating of 900mW. It's in...

Reading the blurb it appears that "red rubber grease" is designed to penetrate into and soften rubber parts. That sounds more chemically "active" than you'd want for a straightforward lubrication application.

It's a long way from "simple class A" https://pinkfishmedia.net/forum/threads/that-damned-sugden-again.247122/page-3#post-4150020
