Because what the world and this forum need is more Tweed Deluxes!
After my successful conversion of a single ended console to a PTP 5f1, detailed here, I obtained a push pull console radio/record player from a nice purple haired lady.
This has a Sparton 7250 with push-pull 6V6 output, 5y3 rectifier and a 12 inch 4ohm speaker (And interestingly, a self split output). I initially wanted more of a Marshall sound, but the vast documentation available about the 5E3 pushed me in that direction. I reserve the right to modify it later if I think it overlaps too much with the Champ.
I did some crude testing with a signal generator and I estimate the PT will give me 360-0-360 so that’s more than fine for what I have in mind.
As with the Champazoo thread, me posting here is mostly a way of keeping myself honest and focused, and documenting progress for my future reference. If I end up giving ideas or help to someone else, even better!
Here is a gut shot before emptying,
The chassis cradle was knocked together with pallet wood in a few minutes, and should vastly improve the experience over my last build. Here is a shot after gutting.
My plan is to do a hybrid PTP build, mostly because I enjoy the intricacy and mental puzzle of PTP. I do want to keep my options open for modification so I plan to use the eyelet board to locate some of the most likely points of modification like coupling caps and cathode resistors/bypasses. The 6V6 will go in the two angled holes next to the PT and the preamp will go at the complete other end of the chassis. I am planning on mounting the chassis with the four holes side looking up, like a classic 5e3, and that will require some planning on the cab side to make sure everything fits nicely.
Parts are ordered and will arrive tomorrow, maybe I will have time for some layout work before then (although I am also working on a wicked 1000 pieces puzzle at the same time, so maybe not).
Thanks for joining me on this adventure!
