Volume drop after redplating tubes.

Then check the resistor that pin1 of V5 connects to (68K or 100K, can't tell which from schemtic). At pin1 you should have voltage similar to that of pin 6.

It's 4 on the tube side and 408 on the other side.

I believe g1 is asking you to measure the resistor value and make sure it is correct. You don't need to remove it, but make sure the amp is off.

I just did. No reading on that one. Is it shot?

[The Dude]

If you are on a scale that measures high enough and are getting infinite or open reading, then yes it is shot. Not to nitpick, but please don't use "no reading" to describe your findings. It is not a clear indication since it can mean '0' (shorted) or infinite (open). In this case one can assume you mean infinite/open since resistors don't short.

Sorry about that. My reading was "0".

[The Dude]

0 normally indicates a short?? What does the meter read with the probes hanging in air? Also, what scale are you on or is it auto ranging?

[g1]

Meter should be set for resistance now, in case you are still measuring for volts?

It's a Greenlee 93-606 set to 20k on the ohm setting reading "0.L" I looked it up, and it is a 6.8kohm resistor.

[The Dude]

It should be 68K instead of 6.8K. Resistors don't short, so I'm a bit mystified by your 0 or shorted reading.

[g1]

In resistance, OL is the opposite of 0.
So the resistor is open and needs to be replaced. As Dude said, it should be 68K, not 6.8K. Blue, gray,orange.

Ok, it looked like blue gray red. 0L. is just what is on the screen when leads are hanging.

[92lx50]

There are a couple other resistors around that one that are reading the same. Are those shot too?


EDIT: Scratch that, the others are fine. I guess some 68k's are in order and I'll get back with the results.

Thank you very much everyone for you help with this

OL means Open Line.
ie: no connection.

Got the resistors in today, replaced the 68k and WHOOHOOO! it LIVES!!! Thank you so much everyone for helping me get this beast up and running again.

I'm TRULY Grateful!

Great news and the whole troubleshooting discussion was completed without someone suggesting that the output transformer was the culprit.
