In a fit of nostagia I picked up a 1965 Kay 720. I'm restoring it and doing a few mods to make it more guitar friendly. It needs new power tubes and I have a pair of GT KT-66's I got in a trade that I would like to try.
It normally uses 6L6's, would these be ok, or do the KT-66's have different requirements that would make them incompatable with the Kay?
Here is the schematic.
Also, any mods you might suggest would be welcome. I am going to add bypass caps on the 7199 and the power tube cathode bias resistor as suggested by a friend of mine.
The original Oxford is blown, I am going to put an Eminence Big Ben in it as a replacement. I'll recone the Oxford later down the road.
