you may have just answered a question i've always had about the jcm 800. i had an early one with 6550's. i biased it for 34's and changed the tap on the impedence switch as was mentioned, and the 34's sounded great. then i later bought on of the models that came with 34's stock, and i converted it to 6550 to see how it sounded, and it didn't sound as good as the 6550 amp sounded with them. so when i saw your post i figured the heater current must have been the reason, eh?
