Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: It depends.

One problem with all old preamps of that era is that moving parts like switches and pots are usually heavily worn. My time is better spent designing from scratch (using newer, better parts and technology) than chasing all over the planet looking for replacements. Building new also provides an opportunity to remedy all the issues that engineers of the day either didn't know about or were forced to accept due to the bean counters. I've learned some of the latter the hard way with ham gear. You'd be surprised what was allowed to come out of a transmitter or RF amplifier made in the '50s or '60s, simply because the design was vetted by a factory without access to a spectrum analyzer or 100 MHz scope.

Buy Chinese. Bury freedom.
