  1. there is some info at this link on myles website about how the gt scale relates to the mesa boogie tube color code. pretty much the tubes the boogie sell are in the 4-6 range of gt tubes. http://www.guitaramplifierblueprinting.com/pastinfo.html Thanks, but I think I did recall seeing that long ago and that's where I got that figure of "6". Probably should be a "5". I also brushed up on the balanced phase inverter tube aspects. Sometimes some of the NOS websites will offer a balanced PI for a few bucks more.no prob. i remember asking him about it when i had a boogie.Past tense? What happened?

  3. Myles, if a Boogie owner were interested in a pair of GT 6L6GEs, what would you recommend, keeping in mind the non-adjustable bias? I figure Boogie's fixed bias setting allows for considerable "slop" and a pair of the GT 6L6GEs with a "hardness" of about 6 should do quite nicely, as long as they were a matched pair.
  4. Check out the reviews of the Reverend (Naylor) speakers: http://www.harmony-central.com/Guitar/Data/Reverend/All_Tone_1250_Speaker-01.html Celestion reviews: http://www.harmony-central.com/Guitar/Data/Celestion/ Altecs and Jensens might be worth looking into too. The Reverend speakers are cheap, $59, and supposedly have a nice warm "vintage" sound. Celestion V30s and 90s are about $100. Both Jensen and Altec make very affordable speakers too, Santana being an old Altec guy for the longest time. Too bad about EVM though. THey made tough and clean speakers that really dissipated the power. One of my speaker cabinet favorites are the Boogie/Thiel, which used to offer the choice of EVM or Celestion 90. Very nice little 1x12. Opps, lest I 4-get, you might want to look into "Razor's Edge" speakers. The have a big following in the jazz world.
  5. Yeah, that's the bad Celestion. Kind of a raunchy rock speaker, by design. Believe it or not, and I could be wrong, but some mega-expensive Matchless come with the G12T-75. Huh? That's dumb, and then some. EVM doesn't make speakers anymore. They made the cleanest and best power handling music intrument speakers. Altec is still around, same with Jenson. THe Reverend (Naylor) folks have their own brand of speaker now, as does Mesa Boogie. Celestion V30 and 90 are quite good. Can't go wrong with them.
  6. You might try a 5751 swap for a 12ax7 in the V1 slot, or a 12AT7. NOS 5751s can be had in the $10 to $15 range, and will probably last forever (especially Joint Army-Navy or "JAN"), like RCA, Sylvania, GE, Philips. WHich Celestion do you have? If it's a vintage 30 or 90, I'd keep it. They're pretty "smooth" as is. Now here's Myles with a word from our sponsor.....
  7. Interesting Myles. I have a problem with the older Boogie's controls, or lack thereof. Striking the balance between the clean and distortion settings was always a compromise. Newer Boogies have independant controls for each channel, which I vastly prefer. The Mark IV is a 3 channel amp which is going to be more complex. I wish they hadn't shared tone controls, I'd prefer independant ones for each channel. All in all though, the Mark IV sounds much less nasal to me at lower volumes and doesn't have the gain balancing problems of the older Boogies. Being a jazz player I appreciate its clean channel for archtop use too. One thing I'm sure you are aware of, the Mark IV has much more of it's innards mounted on PC boards. Sure doesn't look like the point to point Boogies of old.
  8. Myles, have you gotten a chance to tinker with a Fuchs? From what I've heard, they are really nice amps, with a Dumble and Boogie kind of sound.Mr Nice Jazz Guitar Guy.......... I love the amps from Andy Fuchs. I think they give a lot of that Dumble quality, and I prefer them over some of the other "Dumble copies" as they are very price effective and very nicely built. They are much more versitile than a Mesa type front end also, and more articulate to my personal style. I think the Fuchs stuff will go up in price pretty soon, maybe in 2004, as they are still somewhat underpriced for the level of quality and components used. At this point they are still something of a nice bargain. Myles, what might you think of the "holy grail" Boogie Mark IIC+? I have one but prefer my Mark IV, vastly.

I'd love to see him make a rackmount tube preamp, an "affordable" one at that. He still modifies existing amps too at affordable prices. Nice to know.

  11. Oh Myles, why is it necessary to always have a load connected to a tube amp, when it's perfectly safe to powerup a transistor amp with no load? Also, if memory serves, tubes need a transformer on the output for impedence matching, where transistor amp have no need of this. Why is that? They didn't teach us tubes in school. Tube do need a load, i.e., transformer in most cases. Transistors can be direct coupled to capacitor coupled. This is all covered in detail in my Tube Primer section II. Hey Myles, do you like the Monteleone pics? I think this one is a "Radio Flyer", going for a paultry 15 grand. If this was 1999 all over again, I'd actually consider it!

  13. Caevan O'Shite........... Well I won't touch that...... Hey Myles, who had the first master volume amps? Boogie? Traynor? Bogen?
  14. Download part 2 of my tube amp primer off my website, it is all there.[/QB] I looked on page 52, but that didn't really explain the usage or rationale of the phase inverter.
