Members Slaymoar Posted October 15, 2012 Members Share Posted October 15, 2012 After a 5150 combo clone dilemma, I finally settled on a design I had been working on before; a continuation of my original Tomahawk build. If anyone recalls, the tomahawk went through a LOT of changes, and later turned into a prototyping bench. This build is going to be the cumulation of what I ended up liking the most. At the moment, the circuit is pretty much a 6L6/KT66 JCM800, with a big low end, and more gain. The beauty of it is that it has the low input like the JCM800, and essentially can be selected to sound like a plexi/bassman. Excellent pedal amp with the low input. The high input works the same as the JCM's, but more as a "boost" function than anything. Adds treble to the signal, while riding on top of the plexi-ish tone. There are 5 toggle switches. Two of them toggle the brightness of the amp, one changes the character of the gain crunchy/smooth, one adds the jose zener clipping (experimental), and the last is the bass boost circuit. Knobs are: Gain1, Gain2 (not needed, but there for pedal flexibility), Master, Treb/Mid/Bass, Pres/Res. There is an effects loop, and it is integrated into the design and is part of the overall tone shaping of the amp. It darkens the amp up a bit which is a good thing to me. There is also a signal level in the loop. This time the build should look pretty decent, especially compared to the tomahawk which was a mess inside. At the moment I am waiting for shipping confirmation for tube sockets and the actual turret board material, otherwise I am ready to start. Stay tuned if interested, I am fine-tuning the layout and will post progress as soon as those parts come in. Paint is army green, and the theme won't look good until I am finished. I think its pretty sharp. Added Oct 18th: Did the labelling, the main filter cap, most of the PT and some OT, the bias circuit and a few other things. THe pictures have really {censored}ty lighting and make it look pretty crappy... whatever, here is my current progress. Link to comment Share on other sites More sharing options...
Members Slaymoar Posted October 15, 2012 Author Members Share Posted October 15, 2012 Update: First vid: [video=youtube;W8P-X9oFATQ] Some more tweaking left, but should be quite minimal. I am zeroing down on what I want, happy with the results. The feel of the amp is awesome, very responsive and quick, and just a little pick squeal a-la mark series. This amp is kind of a mix of all amps I have liked, borrows from many different designs but in the end its just my own flavor. I started off with a JCM800 type, then looked at the one wire mod plexi, and added my own stuff. Link to comment Share on other sites More sharing options...
Members Slaymoar Posted October 15, 2012 Author Members Share Posted October 15, 2012 I listenned to the comments of "harsh" and "no bass".. I had time to mess around and tweak around.. I realize that I had the mids a bit low on this, I'll make another one later. [video=youtube;lpcjtjgMBJs] Link to comment Share on other sites More sharing options...

Members Slaymoar Posted October 16, 2012 Author Members Share Posted October 16, 2012 I miss your wife face avatar Why did you scrape the 5150 plan? But yeah the 5150 ended up not being as versatile for my needs and this amp will suit me perfectly, and I also wanted my own unique build. Its nothing new, but its still mine.

Members Slaymoar Posted October 19, 2012 Author Members Share Posted October 19, 2012 Updated OP.. Still waiting for the main turret board, tube sockets, shielded cabling and a bunch of other stuff. Next week I think im ordering the tubes. Thinking shuguangs for 12ax7, and torn between gold lion or JJ KT66's.. Link to comment Share on other sites More sharing options...

Members JerEvil Posted October 19, 2012 Members Share Posted October 19, 2012 Thanks, you gonna make a picture thread? Well sure, but as we all know, I'll design it and have it built for me. I am mechanically reetardead. Link to comment Share on other sites More sharing options...
Members Slaymoar Posted October 23, 2012 Author Members Share Posted October 23, 2012 So far, waiting on: Turret board + turrets, heater wiring, shielded wiring, tube sockets, knobs and odds&ends, and I just ordered JJ KT77's, 2 x Shuguang 12ax7b's (CF and Effects loop), and 2 x Tungsol (input & P/I ). The amp can take any power tube in the 6L6, EL34, KT66/77/88 realm and then some, I will experiment with KT66's later. I really hope to receive some boxes soon, they should start landing any time now. Link to comment Share on other sites More sharing options...
