[solved] New Crack Build - High Voltages

[gtrubov]

Hello all.
This is my first bottlehead build, and my first time posting on the forum, but I would like to thank all of you for the help you have provided me thus far in my build by way of the old threads that I have read through.
Unfortunately, I have run into a problem that I could not find already addressed on the forum. The problem is thus: ALL of the nonzero voltages are consistently high on my voltage check.

This is a stock crack build (with the exception of the "mod" mentioned in footnote) fused with a 1A 250W quick-blow fuse.  I am in the USA so this is 120V mains with the corresponding kit/transformer.

My resistance checks are as follows:
Terminal [Reference] Actual
01 [ ] nonzero
02 [ ] nonzero
03 [ 0 ] 0
04 [ ] nonzero
05 [ ] nonzero
06 [2.4K] 0/2.47K*
07 [2.9K] 2.9K
08 [ 0 ] 0
09 [2.9K] 2.8K
10 [2.4K] 0/2.47K*
12 [ 0 ] 0
13 [to 270K] climbs
14 [ 0 ] 0
20 [ 0 ] 0
22 [ 0 ] 0
B3 [2.9K] 2.9K
B6 [2.9K] 2.8K
RCA Earth [ 0 ] L:0 R:0
RCA Center [90-100K] L:106.1  R:105.5
*I added a ground to the unswitched side of the TRS terminals. Values are unswitched/switched.

Voltage check:
01 [75-90] 176
02 [170] 385
03 [ 0 ] 0
04 [170] 385
05 [75-90] 174
06 [ 0 ] 0
07 [100] 234
08 [ 0 ] 0
09 [100] 235
10 [ 0 ] 0
11 [ 0 ] 0
12 [ 0 ] 0
13 [170] 384
14 [ 0 ] 0
15 [185] 432
20 [ 0 ] 0
21 [206] 479
A1 [90] 173
A2 [ 0 ] 0
A4 [ 0 ] 0
A5 [ 0 ] 0
A6 [90] 174
A7 [ 0 ] 0
A9 [ 0 ] 0
B1 [90] 174
B2 [170] 384
B3 [100] 233
B4 [90] 173
B5 [170] 384
B6 [100] 234
B7 [ 0 ] 5
B8 [ 0 ] 0

Also, the Tip of the TRS measured 14V on startup and reduced to 0V.

What am I missing? What could be causing these high voltages? What can I do to mitigate them?
I can provide pictures at request. If it would be helpful, I also have access to a rudimentary (but accurate at audio frequencies) digital osilliscope.

Thanks,
Alex

Check all of your black ground wire connections and look for miswires on the terminals on either side of the power transformer.

Hi Doc,
Thank you so much for your help. Last night I checked the ground paths, which were all okay. I resoldered every joint that I even imagined to be questionable. Resistance checks were all within normal limits. It was at this point, I discovered what was wrong with my amplifier build that was causing erroneous voltage readings, and unfortunately this was not a problem that is within your scope of practise to fix. It seems my DMM had come down with a severe case of Operator Error. I has set it to AC voltage instead of DC voltage. All voltage checks are now within normal limits.
Thank you so much for your help.
