Title: Mounting Boards Simplify Wiring
Post by: PRR on November 22, 2014, 04:57:37 pm
Popular Electronics, 1955.

Early 1950s Fenders used p-2-p construction, late Fenders used eyelet board.

is it possible Leo saw this article (but used different details)?

Makes sense to me, timing looks right.

Maybe an earlier iteration of a similar article prompted Leo (or perhaps something he saw when repairing radios or looking at the innards of his test equipment).

I say this because I used to have a 1954 Princeton, and it used an eyelet board inside.

Thanks for the time-line point.

Some of the material in PE is obviously recycled from other sources, or common-knowledge among insiders being put out to a broad audience. So as you say, he may have found it elsewhere sooner.

This is supposed to be a gut shot of a Telefunken V41 amp, which went out of production in 1949:

I've read that some of the gear Altec made for movie theatres in the 1920s used eyelet boards, but I can't find any details on that, other than a brief mention in Wikipedia.

I saw some WWII electronics gear in an Air Force technology display at Wright Pat AFB years ago, and I'm pretty sure I saw turret boards in some.

i believe hammond used tag boards as early as 1935-36 - look at dr20 tone cabinet amps w/ RCA Jensen 2A3 and 56 powered amps.
