I got this 410/115 stack about a year ago for crazy cheap money. So I had to have it. It's from 1991 and came originally from some rock guy... Pat Traverse, I think, who had a deal with Peavey. Anyway it needed some attention so I sent it to my amp tech here in town and after he repaired the minor damage to pots and inputs I swapped the original shot power tubes for Mullard Reissue EL 84s and put JJ AX7s in the pre amp slots. Man what a difference. The Mullards made it dark and crunchy. This is not a harp amp and needs some signal massaging on the way in (Harp Sheild/analog delay/Butler Blue Tube with AU7) but it really sounds amazing. It's fun to tame the beast. Now all I need is a fork lift.

Try this preamp tube configuration (JJs): AT7 D/W7 AT7. That should make this amp harp friendly AND allow you to use the drive channel and boost switch for harp. If it's still too hot for harp, just put a Mojo Pad between the mic and the amp. This has worked extremely well for my Delta Blues which has similiar circuitry,.

I'm thinkin you meant EL34's. There are many big amps that will work for harp with the right adjustments. I love big amps! Go Man Go !!

I had a '91 C50 410. The power tubes were two EL84s. I know what you mean about the forklift. My combo weighed 70lbs. Like Barley said, "Go Man Go !!"

I thought it took 4 EL84s.

I played through one of these a few times in the late '90s and thought that with stock tubes it was too gainy and feedback was an issue. Since I didn't own it I didn't try tube or speaker swaps. It WAS loud, though.

HVYJ, I am interested in the Mojo Pad, but I think the Butler Blue Tube functions the same way. It also acts as a compressor (no idea why) which is very helpful in keeping the volume spikes out of the final signal. So I get to decide how clean, how much of the tone is harp, and how much is from the amp. Generally the grittier, more articulated tone from the mic is the result of the BT turned up to about 7. For a fatter deeper tone I turn the BT down to about 4 or 5 and crank the amp to about 8 on both pots. Lots of options anyhow.
