Very pleased to introduce my completed Hotrod 1272. It's been completed for a year now except for the non-functioning DI. Last week I gave up and performed an ugly kludge to get the DI in service. I'm very thankful for every one who helped out, allowing a relative newb to build a top-notch pre. Thanks especially to Greg S. and JLM for bringing the hotrod mod to the masses, NYD for help with the relay power, Fabio for the BA283 board, Rascal Audio for the Texas Marinair copies, and Charlie for the asskicking relay boards. (!!!)

overhead shot - planned on doing 2 channels. Cutting back to 1 = a cavernously-empty enclosure.
front-panel left
Supposed to be a cheesy, videogame "level up" graphic, but it didn't transfer - only the words came through.
Learned something about lasertran: shades of grey come out completely clear. (?!)
switchbank
power station with Handcrafted Tone's PSU board, and separate board for relay 12v
switchbank - overhead shot fromt the inside
closeup of DI board with embarrassingly chaotic wiring, and hacked switch to power DI relay manually
relay board, line amp, and output transformer
underside of relay board
relevant threads
10468 Relay PCB
Relay switching transistor schematic from this post
getting a simple 12v for powering relays
also, a rather pointless video demonstrating the non-functioning DI switching, which I finally gave up on.
(eventually I will rebuild the DI board to get it working, but for now, here's my 'get 'er done' method.)
