I have what I believe is a 40 watt Sonic I - since in an earlier post Conrad worte that the 40 watt model uses the 7199 driver tube, and this is what is in the amp. Problem is, I picked it up in the late 70's and it had no Power Tranformer in it. It appears that the previous owner hacked it up a bit and must have toasted the oringinal PT. Can anyone tell me what PT I can use as a replacement? The Output Transformer is a Dynaco A 470.
Thanks
