After many years of service in my project studio my 2:90 stereo amp is giving me fits.I started getting sizzling, sputtering sounds on Channel B. I tapped on the 6l6s to see if any tubes might be suspect. One 6l6 seemed to stick out, so I pulled it and found the base to be a bit loose. I...

Greetings fellow Mark Fivers. I'm sure this has come up before regarding channel switching pops by way of the footswitch. I bought a brand new V and right out of the box it exhibits the "pops", no matter what channel settings or wattage settings. It's an annoying thing. Before I call Mesa...

Hi, Ric here. Besides my Mark IV; and a Recto Pre/2:90 thru two Tone Tubby 12s rig, I have a LSC with 2-16 ohm Celestions in it. Like others I'm not 100% happy with its overall tone at times. The Reeder mods sound interesting; maybe a speaker swap might be the ticket. Not having the specs here...

Ric here. I have a Mark IV I bought in 1990 that seems to need some maintenance. The foot controller doesn't work correctly;manual operation of the rotary switch in the back of the amp only works for channel 1,otherwise I get an obnoxious hum;the amp itself emits a low nasty hum, I can't turn up...

Greetings fellow Mesa users. I have a few Mesa amps. Pertaining to my Lonestar classic 2x12: Has anyone swapped out the stock Celestions for other 12" speakers; for example EVs? I've always loved the sound of EV speakers like the Black Shadow EV in my MarkIV. Thanks for any "feedback"...

Greetings, Ric here. I have a MarkIV combo,purchased new in '91 or '92 that seems to need some major going over. In the past I've replaced various pots(due to the plastic shafts getting sheared off in transit); I've replaced the rotary switch that selects modes for the foot controller(which...

I sometimes "Slave" my 2:90 to my mark IV. Here's my setup: Cable out of Mark IV Slave output jack to Yamaha UD Stomp. Two cables out of UD Stomp(left and right output jacks, for stereo),to the left and right line inputs of the 2:90. I turn the slave volume control knob almost full bore. That's...

Hello, Ric here. I had problems with channel switching (mark IV 1990), T :?: urned out to be the channel select rotary switch in the back. I ordered a new one and installed it. All was fine untill 5 years later-now that one has gone bad(or so I hope): I ordered another one a few weeks ago and...

I contacted Mesa Tech Support yesterday to order some parts and regarding my three questions: 1: Yes the 1/4 inch jack on the chasis is for EQ switching a sattelite cab. 2:Regarding the two 4-ohm speaker jacks: Of course you can hook up two 4-ohm speakers but in the case of using 8-ohm...
