bassman 10 project OT issue, HELP!

[friction.usa]

so i just picked up a broken bassman 10 for $175. it powers on an is loaded with the original vintage speakers in perfect working condition but the power tubes will not heat up. i'm not much of a tube amp repair expert but have had a similar problem with an old sovtek mig 100 in the past so my best guess was the OT is blown which can be a pain to replace. but as i was checking the amp out i noticed that it had been a little smashed around and the guy i bought it from said that it worked until the movers moved him into his new house. so it possibly could just be something was banged loose or there is a broken connection that needs re-soldering. i opened it up and nothing looks to be noticeable loose or out of place, so i guess no matter what the problem my be i am wondering two things...

1. anyone have any advice that may help me to self diagnose the problem and possibly fix it without having to dish out 100+ in labor to a shop

and

2. if it is a blown OT any suggestions about what the best reasonably priced replacement OT would be, i would like to keep as true to the original tone of this amp as possible

any help would be great and much appreciated

thanks

Output tubes will not heat up but the preamp tubes will? Is that right?

[friction.usa]

yeah it powers on and the preamp tubes will heat up but the power tubes won't.

Have you tried replacing the tubes? Getting "smashed around" can ruin a good tube pretty quick. That's the first and easiest thing to check. To get further into it, if you have a DMM, check to see if there's voltage at the heaters, plates, etc. Don't touch the filter caps.

The other point to be remembered is that some Bassman 10s had a pretty weird impedance thing going on so an output change to one of Teddy Weber's 018343 transformers could open up some new territory for you, impedance wise.

i tried a new set of tubes and it didn't seem to make a difference.

...sounds like the twisted-pair green "filament" wires (6.3VAC) going to the power tubes have an "open" somewhere...check them (or have a qualified tech check them).

I second a new output transformer. Never saw one like the ones in the Bassman-10 before nor after. We'rd stack, shape, impedance etc. Get a Mercury, Heyboer, Allen, replacement. Weber ehh, if you're on a budget.
