My new (old) signal jenny

Kyoritsu K-128. Arrived in the letterbox today. Haven't fired it up yet, but the seller told me it was working. I'd like to find a schematic (it uses a 6x4 rectifier, a 12AT7, and a 6BM8). Looks like its been recapped at some stage. Thought it was worth a few hi-res pics (sorry tboy).

(Edit - well I just fired it up and it works perfectly, but I'm still on the hunt for a schematic just the same)

FWIW Found a 'schematic' here: Audio Generator K-128 Radio Kyoritsu, Tokyo

Nice piece of kit It looks like a Japanese tribute to the HP 200C. Just right for working on tube audio gear.

Nice old generator...you definitely should replace all those oil caps, tho...glen

Looks like a dead ringer for a Lafayette T-22 - at least from the front, so if anyone has one of those schematics, that would probably suffice. TIA.

@ Mars - would they be all the grey caps?

Long search is complete. Free download here (even tho' it says te-22, its the same thing):

Sweet... I'm experiencing funky old stuff envy. The best thing is that it's easy to troubleshoot and service should you ever need to. If my transistor unit ever fails I probably won't try to fix it.

the simplicity is pleasing
