Swapping 6550s for 6L6s?

[CitizenCain]

What needs to be taken into consideration for converting a 2x6550 amp into a 2x6L6 amp?

I've got a Sundown head using 6550s. I'd like to tame it down a little to use with some lower wattage cabs I have. Plus, I'd like to warm up the tone a little, the 6550s sound a touch stiff.

Thanks for any info!

6550s can take greater voltages than 6l6s so you'd want to make sure that the plate and screen voltages were within the design parameters of the 6l6. Do you have a schematic or voltage chart for your amp?

Yeah, I do. I'll have to ask some techie friends to help me check that out. Thanks for the tip!
