    Hey all, I thought it would be fun to see what you all would like to see next for a build thread.

    Amp 1 is a JTM45 with Heyboer Radiospares OT, Sozo caps, and NOS AB Carbon Comps.

    Amp 2 is my take on a Cathode Follower amp. High plate pre and OD. 2 tube spring reverb.

    Amp 3 has the EF86 channel of a DC30 and a 50 watt plexi with dpdt mini switches to go from Bass to Lead spec.

    Amp 4 is the 12ax7 side of a DC30 and a Classic or High Plate clean (can't decide which to do yet).

    Wouldn't an SSS w/ OD pretty much be just an ODS? I'm not really up on my Dumbles.

    In the end, I'm a Marshall kinda guy at heart so... JTM45

    Hulakatt, well this one would have a cathode follower after the phase inverter like an sss, which would help to keep the power section from clipping. It also extends highs and lows.

    I used to have a JTM build with a Marstran RS OT and Mustards. I miss the cleans of that amp and hopefully this next one will get close to the 3d thump that one had. I learned a few things on that one about how primary impedances affect the tone of different tube types. The RS OT has multiple taps for primaries. I spec'd the new OT with 3.4K, 6.6K, 8K primaries. I plan on selecting them with a rotary switch. Kind of overkill as the changes are subtle. Here is the one I still pine after:

    The correct answer is "YES!"

    ;)

    I'm not up on my SSS/ODS amps, but the others each excite me a great deal. You can't deny a great JTM45 and a Matchless-based design is always a winner (as long as you have a stash of EF86 tubes at the ready).

    Whichever you choose, I'll be looking forward to your build thread.:cool:

    Not gonna lie, this is the true answer. I know what my list of To-Build looks like ;)
