NOS Genuine Toshiba 2SB554

[K-amps]

Hi Guys: I have a few dozen 2sb554's. I do NOT have the complement 2sd424's. Just the PNP B554's. These are among the best sounding TO-3's. The MJ2119x series are close, but not as good.

Same batch in bulk packing. These came from an Adcom Warehouse when they closed ops in the USA several years ago. So they will match that era GFA555, 565, 585's very well.

$10 each. Min order Qty = 4

Ten or more $7.50 each. +shipping

I can trade 1:1 if you have 2sd424's NOS. If you have used, I will trade 1:2 for these new unused ones.

Currently shipping only to the USA.

Inventory left 30 pieces

Did some tests for due diligence. It meets and exceeds spec

Vce spec 180v
Vce tested 232v

Hfe spec R=40-80, O=70-140
Hfe tested= 142 @ 10ma base current

CE junction (cob) capacitance spec = 450pf
CE junction Cob measured = 532pf
