2017年8月24日 · I just learned that JJ is producing a 6SL7! This is big news for me because I use 6SL7s in every amp I build. I've been using the very good but expensive Tung Sol new production, and I'm very happy with it - except for the price. I tried the much cheaper Sovtek 6SL7 and found them to be completely unusable - noisy, microphonic and crappy sounding.

2010年9月21日 · I'm finally getting around to retubing a '64 Ampeg Jet J-12-A. The amp sounds very good, but one or more tubes are noisy with certain notes or chords. At rehearsals it's no prob., but I'd like to get the amp so I can record it, and that will take some quieting down. I've swapped tubes in and out...

2020年8月18日 · Hi all~ While i know there are probably NO direct drop-ins for tubes, except for the 12**7 family, and that different rectifiers, if acceptable to the circuit, can change the amp's attitude, albeit not greatly, I am curious about the 6SC,SN,SL,SJ7 family. With appropriate design tweaks, which of...

2016年11月2日 · This RCA has no model codes or etched glass codes that I can see. I do see the MA on the base. This is from a 50s Magnatone MOTS 8" 6v6/5Y3 amp, model A-646. Not a ton of info available online for this amp... Once determined whether 6SL7, 6SJ7, 6SN7, or whatever I have some follow-up...

2017年3月25日 · Frenzel. You can order up most of their amps when built with the "RETRO 6SL7 PREAMP UPGRADE - replaces 12AX7 preamp tubes with vintage 6SL7 "big bottle" tubes for the 40's-50's vintage Les Paul tones. Add $60.00" option.

2017年10月5日 · Got a matched set of two 6V6 RCA NOS tubes for half the price or less of equivalent glass versions. They are not microphonic in any way - (some propaganda would have you believe otherwise), and they are super strong and superb sounding. I think they have largely been overlooked in favor of...

2023年11月24日 · Sometimes, $385 gets you a cool vintage amp. In this case, it’s an Ampeg B-12XT. I’ve been lusting after a B-15NF at my local store, and wondering if I could find the same magic for a fraction of the price.

2016年12月27日 · I've ended up with a small collection of vintage Ampegs. I have several tube configurations - one with 12AX7s, several with 6SL7s, most with 6V6 outputs. I currently have a Celestion Blue in one, and really like the sound of that. Which speaker of these three would you recommend for this...

2015年7月15日 · The tolex is a bit rough around the edges on this early R12R Reverb Rocket...but the workings are in excellent condition. It's been re-capped and while it came with the original C12R reconned...the recone still, unfortunately, sounds like a C12R :) So I pulled that old guy out. After quite a bit...
