Plates
Ok V1 and V3 pins6"s now are up in the 400"ds These are the plates that were off corect.Mikey
Re: Express Problems Pictures
Cool!! That explains the lack of B+ in the pre-amp section.
But....without that jumper, you should NOT have had voltage at V4&V5, pin 4 nor at the last 40 uf filter cap (C17).
So....something else is funky. Wondering if whatever that is had something to do with your earlier flare-up issues.
Quadruple check all power tube connections against the schematic. Look closely for any "stray" wires (like...strands from OT wires) that may be making contact with V4 & V5, pin 3 that may be making contact with pin4.
I am about to catch a plane and will be out of contact for a while but hope that someone else can jump in and help.
Good luck,
Dave O.

sorry
Sorry Mark,These pics Suck!
Re: Express Problems Pictures
Mike what is that second red wire on B+5 that does not go there that goes under the tone board to the presence pot from the 8 ohm tap on the impedence selector.

Re: Express Problems Pictures
one really bad problem is, you have the 100k resistor in the wrong place where the tone cap section is. the 100k goes between the 500pf and the 2- .02 caps. You have the 100k between the 2 --.02 caps, and on the end of the cathode resistor on the end of the board..
Re: Express Problems Pictures
Yes resistor R4 is misplaced. Good catch Richie.Richie wrote:one really bad problem is, you have the 100k resistor in the wrong place where the tone cap section is. the 100k goes between the 500pf and the 2- .02 caps.

Re: Express Problems Pictures
Richie your correct, I checked the rest of the board and it appears good on top not sure about the B+ wires below. The cap stack is right.

Thanks guys,Ill get better pics tomorrow,I have to fiddle with the camera,They should be much better,OK Thanx Mikey Also Mark,Your right I removed that wire,That is an older picture.
Tanks Guys
Mark,Do you want me to redue the voltages one more time,We have found several mistakes here(STUPID STUFF ON MY PART
)I could give it another shot,My bigest fear is that I damaged something,Fireing up with diodes incorect ect.Anyway let me know,Thanks again!,Mikey
Re: Express Problems Pictures
Yes lets try this one more time and see how it goes Mike.
With the DMM on audible ohms testing continuity mode make sure the B+3, B+4, and B+5 are correct under the board going to the proper turrets.

Attention
Attention to all you guys who are watching this thread,Mike Cauley is now the owner of a firebreathing monster amp,Yes ,He has got it up and running!!!It is amazing and also quiet,Im not going to do another thing to this beast,It is a ass-kicking amp,Now as I except my award I would mostly thank all you guys,Mark,Jim,charlie.Kenny and rj who is a scoller and a gentleman. Without amp garage and all you guys I could not have done it.
This amp Im running nos 6v6"s and You can do the whole Les Paul roll back the vol,thing,Im just playing through a 2x12 marshall and its sounds amazing.Well Im going back to enjoy this amps Thanx So Much Boys,Mikey
PS Did I mention these amps are FREEEEKIN LOUD!!!!!!
