The Amp Garage

Hello, I recently had to replace our whole house heating system. Among the things to be taken away was a switch box for a radiant heat system. I kept the box which was made of heavy steel. I have previously stripped out an Akai M-8 RtR and had an extra transformer on hand, some tube sockets, volume ...

Hello, I recently did a local Craigslist trade - a turntable for a 1956 tube Bogen MX6 which was in good shape and had its full complement of tubes. All I knew was the other guy said it turned on but he did not hook it up to anything. After the trade, I pulled the 12AX7 tubes and they were original ...

I thought I might add if it was not obvious - the photos are the before the modification.

Honestly, that is about the best and most perfect response I have seen! I think I will do that!

Hi, About two months ago I was at a garage sale and came across a beat up old RCA 400 projector. It was missing the reels and the arms and the belts to drive them. However, I could see that the tube amp was still in there with tubes! I bought it for ten bucks. There was no schematic available for th...

Thanks Tony. I did find that one and it is for Model MI-1305. My unit is a MI-1311 which I cannot seem to find. I even asked Sam's Photofact to research it. I have pulled the amp and it needs work (new caps all around and I need to test resistors). It does put out a modest level of output and all th...

Hi, I just picked up a RCA 400 16mm projector that is driven by tubes! The mechanics are pretty rough for the projector portion so I think I would like to convert it to a guitar amp. I heard one on Youtube earlier that sounded terrific. http://www.ilovefuzz.com/viewtopic.php?f=149&t=29174 I am going...

Hey Phil! Thanks I will try that. A bit cumbersome to get under it now but it is worth a shot. It sounds really good. A lot has happened since I started on this and it is such a relief to get it to a playable spot. Now, tweaking is the goal.

Thanks. The tank is under a piece of 3/4" marine plywood and the amp is on top. Would that be too close?

Forgot to mention I mounted the reverb tank underneath the board on which the amp is mounted.

Hello all, Meet MyHammy! I have solved most of the problems, there is still a little bit of a hum but it is tolerable. I made a lot of changes to simplify. I ditched trying to use the EF86 on a separate board because it was too complicated with lots of wires running to and fro and it gave too much g...

I have several sockets left on the preamp board for my amp. At present I am using just one EF86 that goes through one 22k potentiometer to the amp. That is my only volume control. Sounds great but is not very flexible. To get overdrive tone I have to turn it up very loud. So, I had this thought. Wha...

I cannot tell you how affirming your comment is! I have struggled with this a lot - mostly because of my learning curve - but a struggle nonetheless. Thanks!

Update: If anyone is interested after my epic, far too long string of posts! Disregard the circuit I described in the last post. I have gone simple and have just an EF86 tube driving the pretty much stock Hammond organ amp. It sounds the way I want it to. I will be adding a dwell circuit and a one-k...

Hello: After much trial, tribulations, mistakes, misunderstandings, learning moments and dumb-assery I got it working the way I want it to. Including the reverb. The reverb flummoxed me all day yesterday as I tried to think it through while working at my day job. . . . . . It did not dawn on me what...
