Don't throw those tubes away just yet...clean the pins first. 12ax7 pins can be cleaned with a bit of scotchbrite pot scrubber pad pinched around each pin and pulled off... or a dremel wire wheel in a dremel, holding the tool in the left hand so that the brush rotates toward the tips on the...

Well, they arrived! Have not yet stuck a tube into the c-lator and run it hooked up to the amp, but did have a chance to tube-u-late and fire up the Hot Rubber Monkey unit. WOOOOOOOEEEEEE!! What floored me was not the type of tone that I hear on the youtube demos, I got that right off the bat...

Played out at the local city park at a wake for an old friend a couple weeks ago. Played perfectly and sounded great, er, the amp that is. Put the cover back on and took 'er home. Went to a buddy's house for a jam sesh a couple night ago, when I hit the power switch a loud buzzing...

I saw a screaming deal on eBay and could not resist the GAS reflex...two channels, reverb, 4 el84's, 3 12ax7's, 50 watts. Bedrock amps were made for a few years by musicians in the Boston area. For a short period of time they were used by Aerosmith. They are typified by using oversized...

Recently I won an auction on ebay for a military gizmo containing a dozen Bendix 6094's, two CBS 5751's, and a CBS 5814a. Each of these tubes were covered by an IERC heat shield. I scavenged them and the longer ones are a perfect fit for el84's, a very hot running tube. So I stuck a quad on...

Just got this in today. Check out ebay search 280352662220 Phenomenal machine. Could be considered a Hiwatt tribute amp with a couple of original twists. I can't post clips, but this is the second amp I have gotten from this custom builder using Bendix tubes. Big. bold, tight as can be, and...

No bigger bell ends than the guy asking questions who didn't bother to read the manual first... :shock: It's on the Mesa web site. :wink:

Have to say that I need to thank Dan Torres for his book, Inside Tube Amps. I borrowed it from a luthier friend who had it sitting on a shelf unread for quite some time. In the past I had done some preamp mods in my lowly Silverface, increasing the value of the cathode bypass caps for each of...

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUURRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRGHHHHHH! :cry: :cry: :cry: :cry: :cry: :cry: :cry: Bummer!

Hi, Just curious, I'm hovering like a buzzard on the acoustic/electric Yairi guitars with system 500 or 600 pickup factory installed. What have your experiences been like? Any recommendations? Thanks!

Just recently scored this on Ebay. Search 290230400217 labeled Texas instruments...so here's an impromptu vintage old stock tube ID that takes some tube weenie knowledge to solve... Who made it? When was it produced? What is current ebay market value for the properly ID'ed tube? :?: :wink:

Good read, I also enjoyed the tidbit at the end defining the difference in circuit design between fixed and cathode bias power sections in guitar amps, nice bonus.

Not that Mesa doesn't have a long history of putting nice parts in their amps, but I just did a speaker sub in my Maverick 2/12. The installed pair of speakers were a very fresh pair of nearly new old stock JBL MI 12, 8 ohms, wired in series for 16 ohms, stock speaker is pair of 16 ohm...

I have an old silverface Champ that I have done some major stuff to and love the results. Just curious, are there any other single ended or parallell single ended amp users? What have you done to yours? Built from scratch or kit? Own a boutique type? Fave tubes/speakers?
