Anyone who knows where to find this old Harris or RCA CA3100T 38mHz IC?

I try to renovate two very well sounding NAD's. To a reasonable price , the NAD 3080 was one of the first amplifiers that was able to drive a load in 2 Ohm.

The TO-3's in NAD 3080 : NEC 2SD287 /2SB539 delivers in the "A" version 10 A by max. 120 Vceo and 7/8 mHz .....10A is to the limit when the load is 2 Ohm.

The mentioned TO-3 NEC's are obsolete as well.

Any suggestions where to find TO-3 /TO-204 op transistors with 12A or 15A and the above mentioned specs ..120V / 7/8 mHz?

The 2N6341 is a replacement for the big NPN if you have the b or c version - in stock at Newark.com

Here is a cross reference list. Note there are a, b, c and un-lettered versions of your power transistors.

Thanks for the link.....Original NAD used Harris types in the 3080, but I have asked Littlediode from UK, and he says, that the CA3100T he offers is genuine RCA types....think it stays on the original IC from RCA .

Is it "Newark.com" in Chicago? As far as I can see the datasheets says that 2N6341 does not have a complementary PNP....?? Otherwise the 2N6341 would have been a super transistor for the 3080.

 

Just bought 2 pcs. genuine RCA CA3100T's ....still missing substitutes for the TO-3 / TO-204AA NEC 2SD287 /2SB539..........?
