New (old) signal jenny

Post by tubeswell »

Arrived in the post today. Kyoritsu K-128. Uses a 6x4, 12AT7 & 6BM8. I'd quite like to find schematic. The person I got it of said it is working, but I haven't fired it up yet. Looks like its been recapped at some stage.

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

Thats a good looking rig, nice and simple, I got an old HP 202A I scrounged
from the back closet of a physics lab.

are you a "member" of the web page you linked? could you post the
schematic easily?

My time is short this week.

Hi Andy - no I'm not a member (at this stage) - thanks for enquiring. Will I ever become a member? - that remains to be seen whether I can locate a schematic elsewhere or not dammit. :wink:

FWIW I have since found out that this jenny is a dead-ringer (methinks) for the Lafayette T-22, so if there was a schematic for that one floating around, then that would probably suffice.

Man, that thing is an antique!

I'll bet it lasts another 50 years. :D
