6L6 "twinwreck"

[mac0611]

here is a build I threw together using twin trannies and some other mods. It sounded stiff at first, so I choked the plate supply with a 100 ohm resistor and did some mods to the presence control to give it more range. I also had to modify the load line to get the preamp voltages close to spec. The PI input and output caps are also different, I used fender AB763 values here. I liked the way they made the amp sound. I used 100K grid leaks for the power tube grids so I could run it hard without tube failures. It has that nice glassy chime when played clean, and snarls with really nice harmonics when pushed with a Les Paul. I'll try to post sound clips. Never did it, and I don't have a mike I'll take finished pics and edit the post

here is the semi-finished product, a work in progress...

looks good man, I just hope it will be loud enough.

Cool amp Mac, Hope it comes out sounding great. Would like to hear some clips if (When)you can .

thanks chad and funk. I have a 2X12 cab loaded with EVM 12L classics, and it is my "truth box" The EQ of these speakers is flatter than south jersey and produces the true tones of any amp plugged into it. The twinwreck sounded great through it, but with the efficiency of the speakers, the volume level blew the garage doors off. I plugged my 4X12 loaded with heritage greenbacks into it and it is pure heaven with a Les Paul. I have some noise issues with it that seem to be centered around the bright switch/ vloume pot area. If I touch the wires coming off the switch going to the volume pot, I get some violent crackling noises.

My ears hurt just looking at that!! Great idea, if a little insane!

That was my first thought.

4 x 6L6 = LOUD!

Looks cool!

nothing better than feeling the music blowing past you. Looks nice. Do you have neighbors?

[M Fowler]

Looks good four is always better. Especially 6l6s

Are you running separate bias for each tube or each pair?

[M Fowler]

Never mind I see the four bias trim pots now

yeah, but I crank it up in the afternoon

Looks like their is ample room in the chassis. Is that a Watts "Super" head box? How did you like using it?

Thanks.

[mac0611]

yes indeed, a good observation. I like how it is thick and stout for holding twin trannies. I wish it was wider for better transformer location.

[M Fowler]

Yeah I like Ken's chassis and will be glad when he comes out with some other versions as well soon I hope, haven't bugged him about it this week.
