Will,
I have an assembled Bugle, built from Jack's kit, that I'd be willing to sell.
FWIW, mine has a NatSemi LM4562 opamp in the first socket instead of the stock BB. It also sports resistor "sockets" (currently populated with 47.5K metal films) that allow you to adjust the load by swapping resistors without soldering. Original assembly manual included.
It's always worked fine for me, but I no longer have a table so it's sitting idle.
Reply here and I can call the number you provided.
Thanks,
Joe
