Re: Check shorting pins of tubes
Hi Phil, make some test with DMM in continuity mode on some shorting tubes, but the test don't work!.. When the tube is pulled into the amp , the fuse blowing, so your suggestion is not ok for me.
Someone have an idea for a little circuit for check tubes!
Thanks
R.

Check shorting pins of tubes
Hi all, There is a simple circuit to use for testing short pins of the tubes?
I have a multi tap transformer and maybe I could build a shorting tester.
my PT secondary:
0 - 130V @ 45mA
0 - 60V @ 30mA
14 - 0 - 14V
0 - 9V 45mA
Thanks
R.

Re: Fender Deluxe 5E3 with tremolo
Hi , I tried to wired your scheme today, but don't work , compared to 6g9 vibrato , seems to me the negative voltage on depth pot is missing.( in the schematic lug is on ground!)
Neg voltage is required or not?
