    Version 3 Fisher 400 (S/N 80262) — Selenium Rectifier Replacement & Dropping Resistor Value?

    Hi all, Long-time lurker, first-time poster. I recently found a Fisher 400 on the street and I want to start the process of restoring it. Serial number is 80262, which I understand puts me in the 48001-and-up (version 3) camp. I'm getting ready to replace the selenium rectifier with a W04G...

    Fisher 800C Restoration Thread

    Met an older gentleman who was about to toss out some old hi-fi gear. Sat and chatted with him for a while and he had some incredible stories. Long story short he insisted zero payment for any of the gear, so amongst other things I received a what appears to be pretty mint Fisher 800C. So...

    Realistic Stereo 40/A Selenium Rectifier

    Hey all- starting a rebuild of a Realistic tube amp. There are a few tubes that need to be replaced, as well as the electrolytic capacitors. However, I noticed there appears to be a red selenium rectifier. I have limited knowledge on these, but I have read that aging rectifiers can become...

    Eico 2536 Receiver - How to Bias

    Hi all! received an Eico Tube receiver that looked pretty cool for cheap. I checked all of the tubes (same replaced in 69) and they all pass, albeit the 4 matching pairs highlighted in red appear to have more of an “open” according to my tube tester. Anywho, replaced all electrolytic caps and...

    Fisher 600 Tube Receiver

    I am having my Fisher 600 repaired/restored and ran into a bad selector switch. Tried cleaning it, but no signal passes through it. Does anyone know a source for replacement or suggestion for repair. Thanks for your input.

    Pioneer ER-420 Receiver

    I picked this up recently, along with a much older Pioneer SM-B201. Cosmetically, it looks really good, especially for its age, and all parts are present. I recently recapped and replaced a few other parts on a Dynaco ST-70, so I thought this might be a fun project... until I looked at the...

    Mcintosh MAC 1500 Bad tube? Bias Adjust?

    I came across a Mac 1500 the other day. After firing it up on a dim bulb tester and seeing no issues, I then proceeded to plug it in normally and try to set the bias. It's supposed to be .7v for all 4 of the output tubes. I tried this and 3 of them got there, the 4th tube won't go past about...
