SOLD - Fire Sale: Blue Hawaii project

Ok, the trevails of my Blue Hawaii have been documented in the DIY and meet threads. It's current state is that the psu is good, one channel is fine, and the other has now blown LEDs, and most likely dead center channel components, and possibly a heater trace damaged.

This amp is now dead to me, and selling for scrap parts and tubes. I do not have the time nor inclination to correct anything further.


What is included:

Blue Hawaii boards and psu - working for several years.
Antek 2x275v toroid, with 6.3v heater (See Antek - AN-3T275 for detail)
Amveco 15v toroid
Goldpoint stereo attenuators (x2)
One quad of JJ el34 (4 tubes)
Case, heatsinks, connectors (including a Woo Stax socket)
Some parts (2sa1968 x5, 2sk389 (x2), and various other minor leftovers)

This project has to go to someone who is very experienced in high voltage amps. It IS NOT functional, and one amp board may well be a scrap. The Victoria Magnetics toroid burned, and the replacement really needs to be 325-0-325with 6.3v heater windings, though the 275v can be used to test the psu.

Edit: Pulling the Mullards to simplify the deal.

This is sold AS IS. $400 shipped CONUS - far less than the cost of the parts, and little more than the Goldpoints alone (after fees and shipping).

If the BH is fitted with the stock PSU then you'd need a transformer with two 0-325VAC windings and not a 325-0-325 unit. A center tapped transformer will not work as the PSU doesn't use complementary N- and P-channel transistors but is rather two independent PSU's tied together at the output.

Correct... my bad.

Not sure I would know what all other than the 2sk389 and the 2sa1968, but would throw in a handful of 2sc3676, 2sc3381, and all my stray resistors (literally a box full).

Just the stuff I'll never use because I need to JIT future builds.

Pulled the Mullards, selling the amp with just the quad of JJ - for an insane price.

Update: I have completely disassembled the amp, and there is NO damage whatsoever to the boards.
