DC-5 All Dressed up - Ready to Rock

Post by tbonesullivan » Tue Jun 20, 2017 9:10 am

Well, after years of avoiding it, I finally emailed Mesa Boogie (Thanks Trent!!) and got a replacement tube guard for the DC-5. I had it out a few times, and nearly had a power tube get killed. Seeing as SED tubes aren't growing on trees anymore, I want to keep them intact.

I also changed the tubes around a bit inside to give a better sound:
V1 (input for lead and rhythm): Tung Sol Reissue
V2 (Lead channel): Sylvania 12AX7
V3 (lead channel +efx): JJ ECC83S
V4 (rhythm Channel): 12AX7A China
V5 (reverb): Sovtek 12AX7WA
V6 (phase inverter): Balanced Electro Harmonix 12AX7

I love how the amp looks. I thought about changing the jewel to a faceted blue or purple, but I like the original jewel best.

It certainly howls a bit more now than it did with the Sovtek 12AX7WB in the V2 slot.

Cool! It's nice to get an amp back up to specs.

Do you like the new tube arrangement, even with the added noise?

I haven't really noticed any increase in noise, either background or microphonic. I haven't blasted it yet though. V2 was originally a sovtek 12AX7WB, so pretty much anything would be an improvement.

I just got in some used old stock tubes, so I'm considering putting one of those in the phase inverter slot, but I also have a Maverick 2x12 to think about. So many tubes, so little time. I do have to be more careful with a combo though, as the longer plate tubes can cause issues.

Ok, I misunderstood V2 "howling". Was thinking it was noisy, not wailing. 8)

Tube rolling can become a endless project...

Oh yes, definitely wailing. More crunchy goodness. V3 had originally been an RCA 12AT7 as well, so that may have mellowed the amp as well.

Thankfully I still have the remains of tube rolling from previous amps, mostly lots of Sovtek 12AX7WA tubes / GT12AX7-Rs from new Carvin amps I purchased. I do really wish I had stocked up on Ei preamp tubes and SED power tubes back 10 years ago when I first got into tube switching. New Old stock and ANOS tubes were a lot harder to find back then though.
