|
|
Could someone please post the pin-out of a Sony SD-146A tube. I'm quite sure it's the same as a SD-187 and 07MS tube.
Thanks,

Sencore website says the same thing, but the heater is clearly 6,7... 8 has nothing connected!
This'll be the second error I've seen on the Sencore documentation... P19LCP09 was wrong too.

I got pissed off and brought in a third tube (SD-146A red) in and tested it. Sencore's pin-out for that tube is wrong. I used the pin-out for a SD-187 ind it tested fine.
F1=6
F2=7
K=10
G1=4
G2=5
J, I checked the heater pins on that tube missing a housing with a meter and it's open so the tube is junk. The cut off on that blue tube is crap but the red was fine. Now with that out of the way, I can check that green tube in the 4000G that came back if a new neck board doesn't fix it.
