transformer for Dumble style build

[bluze81]

I am getting some parts going for a Dumble style build, I want to go with a lower wattage such as two 6l6 power, I have an older TRIAD Made power transformer, Number is P-TF22814 It is still new unused,I bought this in about 2005 from CE, would this be ok for this type build, 420vdc @ 240ma 53v bias two green are 6.5v 3.15A Thanks for any help.

My D'lite 44 (2x 6L6) amp used a Heyboer with 325v @300ma.
And the 6.3vac @ 6 amps.

With two 6L6 and three 12ax7 you are looking at close to 3 amps heater current.
So that might be cutting it close.

You are good for two 6L6's and 3 12AX7's. The TF22814 is the Bassman replacement. It should get you about 435VDC on plates as well.

Thanks just wanted to get some input, I have had this transformer laying round still new, I bought it for a guy that wanted and never picked it up from my shop, I think I will use it now, I have been looking at the Dumble Chassis clones for $105.00 plus ship, These look like decent quality at a fair price. Thanks for the responses on the transformer Question, Steve

$20 gets you so much more!

Both the CE and the overseas chassis are cut for 100watt twin iron. If you want a chassis that is cut for you PT talk to Rj:

I think he has some #124 and "ogre dogs" that are cut for 50 watt iron

Steve;Nat's chassis are thin, mounting holes are out of place, it has the wrong power transformer cutout and you are going to have to figure out how to secure the chassis mounting screws. Nevertheless, unless things have changed the PT cutout is actually for a Twin Reverb (022756), not a Bassman 022814.
model.

Caveat Emptor

It can be made to work, but a better choice is here.
