----------SOLD----------
I'm selling 3 pairs of Aleph J populated boards and 2 Antek transformers 600VA 18V (come with hardwares but no screw). Boards are sold as pairs. Transformer is optional or can be sold separately.
MOSFET are measured and matched from a whole factory tube (48 MOSFET). Matched Toshiba 2SJ74BL are genuine parts from Spencer. Quad matched, 10.65mA, 10.68mA and 10.73mA.
All of them are pulled out from perfectly working a 6 channel amp:

I would like to sell them to experienced DIYer, and I will not offer any post sale support. MOSFET might have to be re-soldered to fit your heatsink holes perfectly.
Please make an offer. Thanks!

Hi,
Can the Antek transformer be configured for 220/240V input?
Also, where are you from?
Interested in a pair.

I didn't expect to get so many messages about this. I'll determine the price today and send out messages to who contacted me.
One of the transformer was sold.

Based on current offers and parts cost, I would like to sell a pair for $140 + $10 flat shipping to continental US. It may sound expensive, but I paid $40 for genuine quad matched 2SJ74BL.
With Antek transformer, $190+$15 shipping.
Please make an offer, and the boards will go to the highest bidders. I'll close entry in 12 hours. Thank you.

A mail from SK Spencer in 2015:
Total 3 sets J74BL quad = 3 x 4 x HK$80 = HK$960.
Shipping HK$35.
Paypal fee 4.5% on top.
Total will be (960 + 35) x 1.045 = HKD$1039.78.
