    Cary SLI-80 with one blown rectifier tube, BUT STILL WORKS just fine. How?

    Question for the more tube savvy among us – thanks in advance for your input if you have any. I powered up my Cary SLI-80 integrated tube amp this afternoon, sat down, listened, and everything sounded great. I left the amp on all afternoon, and sat back down for more listing this evening.

    Sherwood S-4400 - selenium rectifier replacement problem

    Recently got one of these all recapped and cleaned up. Turned it on and it blew it's fuse. I'm thinking it could be the old selenium rectifier in there. So I ordered up some 3A 1000V silicon diodes and put a couple of those in according to how (I thought) they're in the schematic. I first put it...

    Rectifier noise in outputs.

    I have an SA-5300 that I've been recapping etc. Just sat down to try it out and it quite honestly blew me away! Sounds really good. Very clear sharp sound stage and deep natural bass.... Only one small problem remains... when there is no sound, I can hear the "pulses" of the rectifier diodes...

    A Few Questions Please

I have a few questions to better my understanding: People refer to the 'main rails' quite often, what and where are they usually located. This unit (Marantz 4230) lit the DBT...

    Yesterday I received my copy of the Guanzo version 2.2 I've read a lot anout it already, but I haven't seen many solutions to many answers. I did find a schematic, but than again a schematic without power- and heater supply. Atleast now I know where to look if things go wrong. Here is the...

    Big DC Power supply. What does this do?

    I have z bug old dc power supply from the 60s. It was originally used for running solid state systems in electro-pneumatic pipe organs and it seems quite beefy. 25A @ 15/13/12v I plan on changing the capacitor bank to make sure it keeps performing well. Though there are a few parts in here...
