New Build no sound

[dcribbs1412]

Hi
new build no sound
must be something simple but
I walked away but its drivin me nuts

voltages
V5-5y3gt-369,390
V4-6v6gt-380,350
V3-6v6gt-379,348
V2-224,186
V1-190,188
not sure whats next checked layout a few times
would really appreciate looks and comments
link to layout is here http://site.triodestore.com/5E3_Layout_Diagram.bmp[url][/url]

Okay so you've got some DC voltages on your output tube and you other tube plates. and you've got a B+ around 380VDC (going by the plate voltages).

Next step is to check your heater voltages. Have you go 6VAC across your respective filament pins? (2 and 7 of the 6V6s, and across 9 and 4-5 of the pre-amp tubes). Are pins 4-5 of the pre-amp tubes soldered in parallel?

Then check your signal path wiring (with a R-meter) for continuity with the amp switched off. Are there any shorts to ground that shouldn't be there?

What are your DC cathode voltages at idle BTW?

Also the voltages on the 5Y3GT - are they measured in VAC-to-ground from each HT pin (4 and 6)?

Is your speaker plugged in? (you don't want to fry the OT)

Based on the layout and the wiring of the bottom side of your board it is wired wrong.

Right side of board in picture compared to left side of board on layout to me is wrong.

Thanks for the response
while posting on this and another forum
I left it on and right after posting
IT STARTED WORKING!!!
this forum seems to have mystic abilities or
it may have been my rewiring of input and or
speaker outputs
I assume that would cause no sound?
I will follow up if anything changes
Again tubeswell, M Fowler
Thanks so much for your time and input

If it is intermittent then I would check your grounds and solder joints.

I would reflow all soldering with a bit of new solder.
Sometimes you get lucky and by doing all of them you actually fix the one causing the problem.

What are you using for your ground point?
From the layout they show a star ground on the power transformer bolt.

Make sure you have the ground wire from the OT (black) to the jacks and from there to your star ground.

Thanks for looking Structo (Tom)
you have been a great help to me on this and Brown Note forums
I think resoldering the input and the speaker jacks did the trick
it is sounding good now
Thanks for your time
Now I need to decide whats next.....
Lightning,AC15,C@men Ghi@ maybe a Rocket
any suggestions?
Man I got it bad

I finished up a 59 Bassman 410 and I am right smack in the middle of the Carmen Ghia build and waiting for my faceplate to start drilling. That should be a great fun project. Also, almost finished with my Fender 5b6 bassman using ptp octal tube layout in cage chassis style.

One other small amp I like is the Matchless Spitfire and I built mine using Ken Watt's layout and his 18w Heyboer tranny set (turretboards.com) I did not go with a kit maybe should have.

Not sure if you are into the Trainwreck amps but the Rocket is my favorite but all three are good. One thing I found out is using Pacific tranny set makes a big difference.

Just kicking some ideas around.
