2sc5200/2sa1943
so far this is the cheapest i have found,
cheaper than future electronics
future electronics ask 60usd for shipping
while digi key ask for about 40usd
so 8 pcs output plus shipping will cost almost 60.64usd
2668philippine money

have a Technical question to H900 and B500 for APEX

between Driver MJE15032 and 15033 is only R27 with 22R and not connected with output, why ? a lot of amp schematics have it,

1. Is it possibile to add 2 pcs. 100R between MJE15032 and 15033 Emitter and connect with output like many other amplifier designs in complementary output stage have ? what happenend if I will do it in your design ?

2. I want add 220R from MJE15032 Emitter to output and 100 R from MJE15033 Emitter to output for driving Quasi complementary output Stage with BJT or MOSFETS

Can this work with H900 or B500 ?

3. I missing 100 R to base from MJE15032 and 15033 Driver, why dont you have it in your design ?

a lot of schematics have 100 R to base from driver or is it redundantly in your design ?
