During the holidays, i bring home a non-working, hugeass radio from my grandparents. A stamp says it was checked in 1976, but since it has been built during the socialism, the design, parts could be even more older.

It have about 4 pedals worth of parts.

My first question:

What are those vintage electronical parts which could be better than the new ones? (in terms of build a vintage pedal) /for example, i dont think a simple resistor would make any difference, but a transistor could/


So far i "mined" out 5 germanium like transistors. (there is 4 more, si like transitors in)
They have names like this:

AC180
AC180B
AC181B
EFT 322D

I haven't heard any of them, and google failed me more or less. Is any of those could be useful?

Most people think that using vintage parts gives the pedal "mojo" and will make it sound awesome compared to the same circuit with modern components. To an extent, this is true.

You may wanna check some of those components (like caps and resistors especially). They may have deviated a great deal from their original or marked value.

I have some old-ass wax/paper caps, resistors, and some freaky-looking diodes all from a '50s signal tracer. It's awesome finding stuff like this, isn't it? Good luck, man. Use those trannies in a Fuzz Face clone. I bet that's sound pretty kick-ass.

So the components don't have any advantages in itself (except the transistors) it is just the possibility/luck of using "mis-valued" stuff will give great results?

My other question would be about the transistors: Should i solder one pin sockets into the transistor holes on the PCB and swap those different transistors? (i dont know any information about them, dont know whether they PNP or NPN. Could i measure whether they NPN or PNP without destroying them?)

Pretty much, yeah. Although age seems to have good effects on how components sound.

Yes, socket the transistors. If you have a multi-meter with a Hfe function, you can test if it's NPN or PNP by trial-and-error.

I think all those are PNP, though. Old-assed electronics rarely used NPN because it cost more to make them than PNP at the time. The original PNP Fuzz Face used AC128 trannies, and most of those you have there are ACs. The letter at the end of the name (the B's and D) are the gain rating. B is medium-gain, iirc. C is high-gain. Those letters aren't used much anymore, tmk.
