Just guessing the kt66 can run at 550v and if you have them at 365, maybe that's why they are a bit crunchier. Sound good you have it running. I would have gutted it and made another 5e3 probably. Last old amp is now a 6v6 bassman in a Marshall style head, almost done except for biasing and nfb switch.

Too bad mine doesn't have a nice looking chassis like that. :lol:

I've been poking around a bit more, researching different amps, and I have found a few examples of Valco amps that used a pair of 6L6 with a 5Y3 rectifier and an undersized looking output transformer.
Here is one example: https://reverb.com/item/19448307-1963-a ... ensen-c12q

So, maybe this thing did have 6L6s. Still not totally convinced, though.
