Turning on for the first time , going thru the start up procedure, good until I put in the tubes , speaker , no voltage on the second 50uf cap on the + terminal . With my fluke 112 meter set to capacitance , I am reading 50.7uf on the board . up to now everything was reading as described .The only thing I can think to do at this point would be to take out the board and see if a jumper came off . Doubt it . Would appreciate any trouble shooting Ideas .Thanks ! John

Check your jumpers on the board. Use the continuity function on your DMM.

Some how I left out the jumper wire from c1 r2 to r1 . Some how I put a jumper from c13 to r23 by mistake instead of c12 to r23
Hope nothing was negatively effected . Proceeding with startup ,the 2nd 50 uf will function with the power level . Next , tried the guitar and nothing yet , the amp is quiet ,the speaker is quit .

Probably a jumper missing still or a wire missing/going to the wrong spot on the tubes/controls.

I'm getting proper voltages as indicated on drawing , VRM functions , when I touch the c. comp resistor with the multi meter probe , I hear it thru the speaker being amplified( yay so close) . I did wire the impedance switch for optional wiring . I went over the board . Not seeing anything wrong .
