“I thought you might be interested in this. I used the transformers I recently purchased from you for this build. It is a Fender Princeton/Deluxe Reverb hybrid, no tremolo, built using 4 sub miniature dual triodes valves in the preamp with 2 x 6AQ5 miniature output valves cathode biased which should put out about 10 …
“The amp was in no way noisy. I used it for a lot of recording for this reason and never had to notch-filter it. After upgrading to higher power it was slightly, but no more so than typical new guitar amps. It was looked at by a guy who works a lot with valve hifi …
“It’s a Trainwreck Express circuit adapted for Russian 6N2P preamp valves and 6P1P, known as the Thrifty Wreck, found the schematic and build info over at www.SEWatt.com. Sounds great incidentally, monster amount of gain on tap. Problem is now I’ve built this I have to build a full size Express.”
David started with a rustic box and a cassette player case. It’s now a stereo amp with 6V6 output valves.
“I found time this week to finish the amp and all is well. Since it’s mainly built with Amp maker parts (with the obvious exception of the chassis), I thought you might like to see the finished product: my ‘Oscillator to AC4’ project. The tremolo circuit was a bit of an afterthought, hence it’s unwieldy …
“Hi Barry, just finished my phono preamp project thought you might like to see it as most of the parts came from you. I had one of your transformers from a previous project and ordered the other parts last week. I chose to house the transformer and a few other parts separate from the preamp …
“I built an amp for my son for Christmas using parts ordered from you. The amp is based on your WF-55 amp using the 5W OT and 15W PT in your small chassis. However, I added a microphone channel. I had to add an extra turret board for some of the power supply filter caps …
“It’s a variant of an Ampeg Heritage B15 with 6SL7 preamp tubes and a 6L6GC output pair. I built it P2P from the schematic, with lots of parts from you. I’m very happy with it, I put some extra filtering in the DC heater line and the LED changes colour when you switch between fixed …
“Some pictures of the completed amp. Worked first time so I am pleased with that, still a slight mains hum going on, not sure if it’s the heater supply or I might try the PSU caps, maybe they’re a bit small (33uF each). I’m using the 190v tap instead of the 275 and it works …
“Thought I’d just let you know I’ve finished my first project with the bits you recently sold me, and have attached a few pics. It’s based on the WF-55 amp, with a Brownface tone stack that can be bypassed to return back to Tweed Champ mode (with a bypass capacitor on the first gain stage). …
“I don’t know if you remember but some time ago I said I’d send you some photos of your amps I’ve made and that I was putting a web site together. Finally the web site is published – http://www.superphonicguitars.com/ “The Meteor is based on the 2 stroke amp as described in Dave Hunter’s Guitar Amp …
“I thought you’d like to see pics of the 1987x I was building, quite a few of the parts are from yourself, most of the parts on the board, wiring kit, hardware kit, switches, fuse holders etc. “It’s got the standard style master volume on the back which works well. Only thing left to do …
Nice to hear about other sorts of projects, too. Here, Stuart has used the vintage-style tagboard cut down to make a classic fuzz pedal. “I’ve not noticed any difference between resistor (composition). Certainly not in this circuit. Choice of transistor makes a huge difference though. “Both the power inverter and the switch board came from …
“I bought a Double Six power transformer and a Double Six output transformer, and I used the Double Six schematic as a starting point. I removed the complete tone stack, added a GZ34 tube, a 5V transformer for that GZ34 tube, added a switch to choose between a diode rectifier and the tube rectifier, added …
“Here is a pic of my little PC amp. My normal thing is my valve radio collection… 30 or more!”
“Thank you very much for all your components and your advice. I finally finished my amp and it sounds pretty good!! Better than I could imagine! Here few pictures of my project, just next to my custom home made guitars. “The black knob on the left of the input jack is a negative feedback loop …
“I’ve been collecting images and descriptions for your gallery. Only Donna-Lee (#0003) has really benefited from parts, but boy, has she benefited. Those Neutrik jacks and Sprague caps have made her just splendid. I went a bit overkill on the orange at first, but have reduced it to just on the signal path. “I’ll probably …
“The January build was a JTM45, it contains quite a few Amp Maker parts especially the board. I used Danbury transformers. Cab was the biggest job, finger joints cut by hand.”
The FireFly is a great little 1W(ish) amp project that’s a very popular project on many guitar forums. But Mike’s attention to detail on the design and finish of his is a very special. “Thought you might like to see a few photos of my finished Firefly amp; as ever, it’s taken longer than …
“I have now completed my project which was the conversion of a Vox Pathfinder 15 watt solid state amplifier having tremelo and spring reverb, to a wholly valve amplifier with approximately the same output power and with tremelo and spring reverb. “The valve complement is 2 x EL84, 3 x ECC83, and 1 X ECC81. …
