NTE210 and NTE211
General subs and not available in matched pairs, thanks but thats not the type of "sub" I am looking for, as of now all the info I have on these parts is NPN/PNP and voltage and the gain group marks on the parts but without datasheets I can not cross them to "good subs". One other note on this amp, 50% of the caps on the driver board were bad in both channels one was blown one was still working. Maybe I should ask if anyone has datasheets on these S1375 and S1376 Toshiba transistors? Thanks Kip, Jeff
Why not at least try the NTE,s they are cheap enough ,then go looking.
I have used ECG and others in the past and most of the time they work but when they do not you can waste a lot of time finding out why. Mostly this is an audio amp using matched NPN and PNP circuits the closer I follow that the longer the amp will last and with smaller DC offset, this amp only has bias adj. and I am only repairing one channel at present so also going for as close to that as possiable and I do not stock many general replacement types and do stock many japanise, american and european transistors in matched pairs for this reason. Actually I would have ordered the NTE if they had matched pairs "MCP" after the number. Jeff
Jeff, I still have a copy of a service bulletin I received from SAE years ago concerning these transistors. The S1375 subs to 2SC1913 and the S1376 to
2SA913. NOTE-the lead configuration is different!!! Hope this helps. tlwThat helps a lot! Thanks Tlw. Jeff
