The Beast Lives!!

Harvested amp & 15" speaker from a 1957 Fisher console. Found empty 2x15 cab & loaded it with the single speaker for now. Awesome warm tone clean, super dirty with D-1 pedal. R-3 Fisher amp with 4 6V6GT's rated at 195w, most likely close to 50w. I'm lovin' it!!!!!

  • Installed the JJ's & giving a mild burn in. Noticed at moderate levels a cleaner & more distinct tone.

  • Did some more research on the Fisher's & found they can run very hot which leads to failures. My chassis in the area of the 4 6V6GT's gets very hot after playing for a while. Harvested a computer fan from an old desk top I don't use any more, elevated the chassis on wood & now have the fan blowing under the chassis in that area. Wow, what a difference, much lower temp in that area!! What's nice about this amp is that there are 3 ac plugs in the rear of the amp, so real easy to plug in accessories like pedals & this fan. I figure this amp is 60 years old, so I had better give it as much help as possible in it's old age because I'm wailin' on it, LOL!!

  • That Gregory sounds like a sweet amp. Be sure to post pics if you hack a mono/stereo amp.

  • I may have to give something like that a go one of these days. I used to have a lot more stereo and mono tube console amps around here than I do now. I've been pretty much cleaning house for the last few years. 

    I feel the same way. Not always the case but the tube stuff usually sounds better to me. My latest favorite is a old tuned up Gregory Mark XV tube combo. It's only around 10-12w (el84's PP) but it's got a reverb to die for.  I have other amps to play with but I just can't seem to walk away from this one.   

  • Thanks Ron, that would be great!!

    Nothing wrong with The Beast, just some tired tubes. When I kick in the pedal, depending on the axe & pups, I get some minor back ground noise at idle, Once playing all you hear is the axe.

    I also have a low watt tube Panasonic that drives a 2x8 cab & it is awesome. Solid state is ok, but a high output big speaker tube job just blows them away!!

  • I'm in! ;)

    What's wrong with the bad one exactly?  Jensen 510's and 610's are really cool finds and tough to come by.They can, particularly G-610's bring really big money ($ 4-5,000/pair)  in the right circles.  Most of those circles ore overseas.   The H-510's are pretty desirable also to the same folks.

    I'll let ya know if I ever come across a single out there.

  • ya Ron, amp has 19 tubes, 8 are for audio circuit. 4-6v6gt, 5u4g, 12av6, 12aut, 12at7 (I replaced with a JJ 12ax7 for more gain) Plan on JJ for the other 7.

    No hum, all is good until I crank the distortion pedal, crazy bad ass!!!! BTW & you prob know, the Jensen 15" coaxial H-510 are worth big bucks, I'm hoping to find one (to fill the second hole in cab) with a bad cone cheap. Keep me in mind if you come across one. Thanks

  • I bet!  I've pulled a fair share of similar old console amps and many are still pretty sound after a little attitude adjustment.  The old coupling or supply caps (metal can) are the ones that are usually getting a bit tired but  if your running without hum, you should be fine for a spell.  A handful of those tubes (on the right side in the pic) are for the tuner so no need to replace those. 

    It's cool as all heck!

  • Thanks Ron, I'm having a blast with this baby!!!

  • I like it!
