Re: 2xel84 rocket

I have a schematic I drew up... I think it's a good schematic although I can't find any build pictures to go with it so that usually means I built the amp then created the schematic after the fact. Consider it as a good starting place but lets have folks take a look at it and see if it holds up as i...

Re: Head Cab in the vein of Originals

Nice looking cabs... It seems that the original TrainWrecks used a bit more of a plain cherry in the cabinets but as time progressed the cabinetry and woodwork sorta advanced.

Re: Liverpool Output Transformer

From my Moose notes: -- the HTS5200 is NOT the correct liverpool tranny. It is an M6 steel stancor style that was for an experiment that KF wanted to do with hi-fi materials. Maybe it was when he was choosing steel for a clean amp like the Rocket, or something else, but it's nothing like what ended...

Re: Liverpool Output Transformer

I've done lots of Rockets and Express builds but only a few Liverpool's so my info on them is fairly limited... what I do know is below. In the early days when the Trainwreck forum was really focused on cloning Wreck amps, the veteran builders promoted the idea that the 6.6K tap was standard for an ...

Re: there comes a time in a mans life when he needs to build an express

... and live it's just not loud enough to compete with a band. Rock or blues would be fine however, which I suppose is it's intended purpose :D M I suppose it's all relative to what kind of band you are talking about. I've found the Express to be painfully loud when played through a 4x12 cabinet (o...

Re: Altec faceplate ebay find to Class D Amp

Similar idea to this one... There is a guy at my church that has the amp his dad built for him way back in the 60's. It is a DIY Super Reverb Preamp into a Dynaco HiFi power amp. Both the preamp box and the Dynaco box are mounted into the same cabinet. The Dynaco looks to be entirely original and ov...

Re: Altec faceplate ebay find to Class D Amp

Cool idea Mark - I've used a lot of those MeanWell DC supplies and they are really handy... The Altec takes me down a little memory lane journey from back when I was in college. Our PA amp was an Altec with a built in 6 channel mixer along with a couple of the "Voice of the Theater" cabs. We didn't ...

Hardshell Electric Guitar "Coffin" Case - Used

Hello All, I've never really been into this sort of thing and will spend the funds to buy something for my Tele that suits my style a little better... Meanwhile it's a well made and nicely padded case - used with cuts, scratches, dings, etc., on the outside but no structural damage. The inside looks...

Hardshell Electro/Acoustic Bass Case - Used - Cheap

Hello all. The bass that went with this case kinda imploded and I think it's time to cut my losses and clean out some space...

$30 for the case and I'll ship it to you for whatever it costs to cover my cost and have it gone.

Re: Monkeymatic Rocket 64

I fixed it. http://images.mentalfloss.com/sites/default/files/w_17.png I added NFB to my Rocket. (Yes, I know I may lose my membership over this.) This sorted the hum nicely. Hmmm... as I scratch my head??? Maybe one of the guru's can help us understand but in the meantime that might be incredibly ...

Re: CT plus FWBR?

Been there, done that, I have smelled the incense and seen the smoke signals indicating that center taps do not play well with FWBR power supplies. I did not have any additional diodes to create the 1/4 voltage option so I took half of my secondary straight to ground. ... in this case I can testify ...

Re: The Mule Driver - aka Fischer Meets Dumble

Thanks for that rj... You didn't report any trouble with squealing so I assume I may have something wrong with my iteration. If the values match it may be a proximity related issue. On to the chopsticks as xtian mentioned before. Tony, nope, no squealing on this unit. This is one of the quietest am...

Re: The Mule Driver - aka Fischer Meets Dumble

RJ, how ever did you do the front panel lettering? It looks like a dremel with the ball, except it's too clean and even. Some kind of template? I know if i tried it i would be making another front panel and looking for my dymo labeler. Good job! This was done with a laser. In this case the wood is ...
