Very Possible, It would be a good idea to post the type of console, Brand & model Number, And the Numbers on the tubes.

Valvo, and telefunkens can be valuable if they are the right numbers.
Worst case scenerio you have a lot of good donor parts for a better project!

For a start you might try punctation and the occasional capital letter?, your post is hard to read to read and confusing.

Apart from that, list the valve numbers and how many of them there are - that will enable us to suggest what you can do.

But first point, you DON'T normally bridge valve amplifiers - they aren't accurate enough, and the output transformers mean there's no point.

hey i apologize for my punctation grammar isnt my specialty .

The tubes i have are 2 ell80 ,3 ecc83 , 1 ef80 ,1 ech81 1 ef89 ,1 ec81,1 aem86 and a few more with rubbed off numbers .

the reason i asked about bridging i should have asked if i could hook up my guitar on both left and right channels simuntaniously without to much interferance .

I cant tell what kind of console it was,beacause there were no tags on it . Now there is a tag on the transformer that says nordmende r 89 not sure if that helps

i would like to make a distortion pedal if i can with the left over parts there are a few resistors and diodes etc




thanx

ELL80's are double output pentodes, so you have two push/pull amplifiers, one for each channel - the ECC83's are audio double triodes, used as phase-splitters and preamps.

Have a look at this circuit which I found with a quick google!.
