Maintaining that amp sounds like a money pit.

But I'd bet it could drive a really loud subwoofer!

I "turned it up" to 4 and thought I was going to literally blow my windows out from the SPL's in the room. It wants to cave your chest in. Crazy.

Fixed! Got fed up and jus replace the tube from the suspect socket and its mached neighbor. Scratchiness and static = gone and the amp is perfect. One of the pins on the tube must've been corroded or something. Wish I tried that a while ago. D'oh!!!

OK. I think I isolated one power tube socket as the source. When I push down firmly on the top of that one power tube the static scratchiness stops. As soon a I let go it starts up when I tap on anything. I checked underneath the socket and looked at all the solder joints and they look solid. Weird.

Replaced all preamp tubes
Cleaned tube sockets
Retentioned tube socket springs (took forever)

Still having the issue. I can tap on anything on the amp and get that static noise.

I'm thinking it may be a loose connection somewhere. Finding it is going to be a nightmare.

HAHA!

Going to re-tension all of the tube sockets and replace all of the preamp tubes. If the noise persists then I have to dig deeper.

I gotta tell ya - for bass, this amp is out of this world. The earth shaking tones this thing puts out are extraordinary.

Thanks. I'll try to investigate further. Photos. Lots 'o glass!

So I picked up a Mesa Boogie Bass 400+. It's a 12 6L6 and 4 12AX7 beast. It wasn't working but I got it really cheap so I took a gamble. Brought it home and opened it up. Noticed one 6L6 was milky and had cracked glass. Went to pull it and it fell apart. Bingo - there's the issue. Replaced the 6L6 a...

Forgot I posted this thread!

I've had the bag for a while now and it works wonderfully. Grab one if you can find them!

That thing is the tits!

Does anyone know of a company which sells protective plastic amp corners with a 3/4" internal radius and no lip? Thanks in advance.

And many more great amps. Jon, thanks for organizing and hosting this. Thanks, bud! I really enjoyed that '64 ...

I had an amazing time with you all. I left early to attend what I thought was my girlfriend's sister's birthday dinner and ended walking in on a 100 person surprise party for my 30th birthday. An overwhelming day and I'm happy it kicked off with this ampfest. So much fun!

A peek at some of the amps enjoyed today:
