Diesel or kerosene will wok if you don't have boiling water handy...

Everything is getting smaller... Pretty soon you will need a microscope to work on electronics. By then, most of us will be gone.

She was from California and graduated from Stanford University. So, no.

Your story is so very similar to others, like me, on this Forum. Go Navy!

We have a Doctor in the house! I completed all the requirements for a PhD in Organizational Management, but the Thesis faculty member did not like my draft thesis (A Contrast and Comparative Analysis of Policy and Manpower Management Across Fifty Recreational Marinas Along the Western Coast of...

Here is a picture of the PL20 control Board. Here is a picture of the PL20A control board. Minor layout differences and a few more capacitors on the PL20A.

Perry, I like how you wrapped the wires around the center posts of the RCA Jacks. It makes for better alignment than stuffing the wire inside the center post.

I believe I have four PL20 Boards. You want PL20, not PL20A or PL20B, right? I have those, too.

Let's get a S/N 15 out into the world!

Lee, do those picture qualify for a "Nuke" failure?

Somebody was listening at full volume into 2 Ohms...

I was only commenting on the response from Old Phaser. My post has nothing to do with any piece of equipment including the Rowland. This was related to the Phase Linear Service Bulletin referencing the Triad G-336 Autoformer which is no longer available or in production. I believe it was the...

Bad potentiometer? Replacements are likely available.

Lots of copper in that chassis.

I think Lee is running his WOA Model One amplifiers as bridged monoblocks. Lee is that right?

Schematics are normally the rule. But many schematics were drawn by engineers before the unit went into production. Then changes were made (not always good) but mostly to improve the actual performance over the design performance. For electrolytics in the Power and Ground circuits, mostly...

There you go Joe, a new project...

I wish these Triad transformers (autoformers) were available today. This is the best substitute in my opinion: https://lightningboyaudio.com/store/p70/UJ20_line_input_transformer.html#/accounts The LBA-UJ 20 is the first official transformer design released by LBA. It's name draws from the...

My research indicated that electrolytic capacitors have a lifespan of 25-30 years. Less if high heat or high stress environments. They should be reformed (working voltage, or a bit less but not maximum voltage, brought up slowly and held for 24 hours) if idle for more than a year for longest life.
