F-4/BA-3 Transistor Kit
Included in this kit are the semiconductors needed to complete an F-4 amplifier or BA-3 output stage, with the exception of the input Jfets, which can be sourced separately through the store. Mosfets were matched in accordance with standard operating conditions.
6 - IRFP 240
6 - IRFP 9240
2 - TL-431
The IRFP9240/IRFP240 Mosfets were matched at the rail voltage and current that the BA3 and F4 articles suggest, specifically, 22v and .4A.
Please note: the numbers on the MOSFETs are ID numbers only, and are not related to their measurements nor their matching
