I'm getting my beloved 1990 MK I RI ready to sell and I want it in tip-top shape for it's new owner. I plugged it in today and I noticed a lot of background noise. Kind of a hiss that gets louder and softer. I don't notice it when I play, but I want to have it as quiet as I can. I have...

Unleash your inner Santana! '90 Mesa MK I with hardwood cabinet. 100 watts with half power and "Tweed" switch Svetlana (Winged C 6l6's) and selected preamp tubes EVM 12L Speaker Gil Ayrn Mods to improve the reverb, smooth the overdrive and keep the bass from getting "farty" (Simple changes in...

I had an oak Carvin X100 with an EV speaker. (Can you say "boat anchor?") Up until recently a friend was still playing through it. The power section is pretty much a standard 100 watt Boogie/Twin Reverb type, but the Carvin preamp has active EQ and a different overdrive structure. I could never...

I'm not crazy about the stock speaker (I put an Altec Lansing 417-8H in mine) and you might want a lower gain tube in V1 and V2. At the least get the best, warm NOS 12AX7 you can afford and put it in V2. I play my Studio .22+ for about 90% of my gigs. It sounds good with everything from a...

My amp is at my practice space, so I can't give you the exact settings, but I run the treble at around 5-7, the middle up around 7 and the bass at 3 or lower. For what I'm doing right now, I'm just using input two with a Tube Screamer for my overdrive. I have an EVM-12L speaker in it and it has...

Use the Slave Out into the tuner. You don't want a tuner in the loop of an amp. It'll just add noise.

Cab, speaker and transformers. I guess it can't be much worse then my hardwood MK I...

You guys are bad. I had no, zero, nada, interest in these amps and thought they were a big step in the wrong direction. "Make it simpler," I said. "Too many knobs, I never met a MK IV I liked." Blah, blah, blah. If I sell my Rivera S120-210, Studio .22+, MK I RI and a Carvin Quad Preamp, I...

Give me the worst case. Hardwood combo with EV-type speaker (What speaker are they using anyway?). How much does it weigh?

My MK I RI was giving me problems recently. Weird noises and loss of power, distortion when you play hard, things like that. I replaced the first two preamp tubes and it's now quiet and sounding sweet. Tubes are somewhat cheap and easy to replace. Start with the preamp tubes.

I don't think the amp cares as long as it isn't getting thrown around or bumped up against other gear. I put my Studio .22+ on it's back when I use my sweetie's Subaru Outback. In my Caravan, it sits upright with other gear keeping it from sliding around. Of course you need a forklift to load...

If you have a sound like firewood crackling, it's possibly a preamp tube getting ready to give up the ghost. You might try some know good tubes and see if they make a difference. My MK I RI was making hissy sounds, then it started distorting when I was playing and the volume dropped. Preamp tubes.

What 12AX7's are you guys using in your Boogies?

It's OK, they're twineing around my guitar neck now. The patterns in the grain of my hardwood Boogie are especially far out! Wow! :lol:

Well, no actual snakes, but it's making a lot of background noise, hiss and high frequency stuff. It seems to be getting worse. I'm guessing preamp tubes, but what else should I check out? Would filter caps do that? Other then that it's sounding great and has no shortage of power.
