Re: NOAD 1986 Mesa Studio Series 22

I bought a used '89 back in '91 or so. I had that amp for 16 years. I had to sell it (and a lot of other gear) when my son had health issues and we needed the money more...

Re: How to install a bias pot in a Rectifier

I notice that photophuckit hijacked my pictures, so I'll repost... I installed a bias pot in my Single Recto today. I used a 50k pot with a 1/2 watt 47k resistor in parallel with the two outside legs. Leg 1 and 2 of the pot are tied together. I used the legs of the resistor to attach the pot to. I r...

Re: Express 5:25+ what speaker to lose the spiky brittle hig

FWIW, I recently bought a 5-25+ head. I have an Ampeg 1-12 open back cab, and installed a Celestion G12-35XC. It is a very even speaker but retains the Celestion character.

The Celestion A type sounds great in the clips I've heard, being a smoother, darker speaker.

Re: Express series being cancelled?

Here it is. I've been trying it though all my cabs. So far I'm liking the Lopo 2-12 (looks like a recto cab) with an M65 Creamback and an M75-65 Scumback. It's been a fun day!

Play loud and often, and that V30 will sound better and better. It also works well in the context of a band

Re: Where to buy a relay?

And I figured, in for a penny, in for a pound!


I bought all the components in the switching and mute circuits. Even in multiples of 10, it cost less than $30 delivered from Mouser.com

Tonight I replaced the 4N33 IC, 4 2N6426 and 2 J175 transistors. Noise is gone. Life is good

Re: Studio 22+ Speaker

I had a 22+ for 15 years, and tried many speakers. The EVM12L was awesome in that amp. I also really liked the Weber Silver Bell 50w ceramic.

Re: Where to buy a relay?

Russ, Don't unsolder all the pots!!!!!! You want lift the board from the rear. Squeeze and push the standoffs through the board - then lift up the rear edge of the board towards the pots. If the wires to the power tube board aren't letting you lift enough - remove the 4 screws on the power tube boa...

Re: Where to buy a relay?

Are you certain the relay is bad? A poor solder joint could also cause these symptoms. Try gently rocking the relay back and forth as opposed to tapping it. If it acts up, try touching up the solder on the pins and look for cracks in PCB/solder joints in the vicinity. Even if this makes no differen...
