Hey guys, I recently got my hands on some BH boards. It's a build I plan to tackle later next year. In my research I've failed to stubble over any BOM's, so I'm looking for a little help from any members that may have one available.

Cheers
John

The best one would be to read it off the pcb's you have and compare it with the schematic on Headwize.
That way you'll catch any errors.

Now you’ve foiled my lazy DIYers attempt at sponging off some else’s hard work.

Of cause I’d use the schematic as a check off list

, but finding an existing BOM would be nice and handy...

Well if you have the original boards (amp and psu) then I'm pretty sure that the resistors were sized to match the RN60/CMF60 Dale/Vishays.
For the non-0.25w resistors you can use dales or Kiwame ect.
The box film caps are (I'm pretty sure) 1Kv Wima or equivalent.
Also I believe Justin changed the 2SA1156's with 2SA1486's as the 56's will be operating very close to their 400v limit (they'll run uncomfortably hot).

Spritzer just build a BH so he'll be able to tell if I arsed any of that up =P

Edit: I forgot, you can also ditch the 2SK389 and just use the singles match really well (thermal epoxying them together is best for memory).

Thanks Tom, that’s great info to have in here.

I'll send a PM this evening. You will have to update as necessary, but it will save you a bit of time... maybe.
