Not much info out there about the M-190- nice score! I just picked up one without the covers and rusted tranny's/ tube retainers/etc. I've started cleaning up the tranny's but think I'll pull them to do a better job. If the choke is still available I think I'll just replace that one. But as you...

Very helpful! Funny about the Mesa Museum- I told Mike a couple weeks ago someone will be able to open a Mesa museum when I'm gone. When I hit a certain # of amps I decided to lower the count and some of my favorite amps sold. I won't do that again and with insane prices for gear over the...

Hey Dave, I've been building up a mesa bass arsenal even tho I'm a guitarist. I like the M2000 with a Bass VI through either the RR 1516 or 2x15. I also have the Fathom and a Bass 400 I never repaired but recently recently picked up some used STR 418's to try out in it. Is the Buster more like...

Chemically speaking maybe lye? Or ammonia? Not sure about that on a frame of an otherwise good driver and I wouldn't be the guinea pig. I picked up a Bassman combo with a 15" celestion bass driver. The "bottom edge" metal is very corroded and 2 things come to mind. Minor amount of sanding in...

The DC B+ rail voltages wouldn't change so it is only the signal volts that are lower in potential gain than you had originally. As for the amps, you are making a wide river bed for the current flow but that does not mean it is drawing the extra amperage it can. It sounds (to me) like you've...

lmao

Walnut? Mark III combo $2200 Blue stripe hardwood. No pics yet so- here is what I found: 22692 and blue marker I've seen ~22500 DRG blue stripe so serial confirms marker Wood- symmetrical marks on top he thought was from putting another head on it and not perfect but good condition overall...

Yw. STR 415 = mesa label on a Sylvania STR 387 - the one to rule them all STR 454 = mesa label on a winged =C=, the best STR 387 copy ever made STR 440 = 2 different tubes with mesa label, a EL34 STR-440 was made but more commonly this is a 6L6GC. I think this is the tube the Express came with...

That tgp thread is one of the better ones. I read the whole thing years ago. I have yet to read an EV thread without a lot of horrible information in it. There is no good archive and guitarists seem to forget EV was a speaker company, not a drivers for guitars company. If you want to know if...

Anyone know when the rectifier cabinetry made its debut? It is said the amp was announced in '91 for '92 so did 1992 also bring the cabs? Both OS and Trad 4x12's and horizontal 2x12 right off the bat? I have a C16645 with March '93 V30's. I thought it was the perfect candidate for new wrapping...

Throw away the color code guide which only gets you sorta ballpark and don't assume they match. Check the mA on every tube if you want them to match. There is no way around that. If this was a old Mark and the winged =C= are the true SED it's a no brainer. It's one of the only tubes made that...

I like my distortion from the preamp tubes and as much headroom as possible from my power tubes and speakers. It's all about choice. I hope after 5 years the OP made his choice. The 5:50 is extremely versatile. I can't see it not pulling off what was desired. The obvious answer was all of...

I bet that purple stripe kicks some major booty. Thanks for replying- this sounds exactly like the R I was talking about that he retroactively upgrades.

I converted and beefed up one of the 4x12's for 12L's. The baffle was old and weakly held on. Then I came across one loaded with the 12L's so I've got 2. Yes boat anchors but localized hurricane transducers. The VS-12 was in the bottoms of many. I would love to have that 4x10. Mesa I believe...

Again just a guess, so a guess on a guess makes a second derivative guess in diminishing value: They removed the R so the factory didn't see the value (pun intended) of it. Like it or not gone stops it from acting as a voltage divider with no path to ground. No Bleed thru. No worry about...
