JP1 Remotes

I think the main thing is compatability with the other parts......I'm sure that even counterfits will do their best to meet the data sheets.

My thinking is that if I get counterfits....then OK....as long as all of the ones I get are the same.

I need a couple more days here to sort through some ...

Thanks....I tried eBay the other day and nothing.....but I was looking for the 2SB755 so It looks like I can get the 2SD845.....now all I need are the 2SB755. Ebay does not show any for keyword search 2SB755 Toshiba and neither do the stores from those two eBay auctions....I tried those same stores ...

I appreciate the help.....Thanks to all of you.

It is 4 Transistors on each channel 2 PNP/2 NPN.

Also the Power Supply is a dual supply providing isolated +/- power to each Channel.

And the two 2SD845 that must be connected to the two tranys that are blown also have slightly less impedance across ...

I was really wanting to learn about repair of this type of amps and you have taught me things I did not know but it looks like this is the end of this Carver amp.

I cannot justify the cost that it will take to replace all the Transistors and after what you said I do not want the amp unless I can ...

The Power Transistors are all Toshiba.

Two on left channel are shorted. I found a Chinese data sheet and these are PNP number 2SB755. So there are 4 PNP total and 4 NPN also. The NPN are 2SD845 and I found a English data sheet for those and if the pin-out is the same for the NPN as the PNP then I ...

OK,

That makes sence too.

Like I said I hope not to be a burden.

I will check the main transistors for continuity.

I'll report back what I find.

Thanks!

I understand bleeding the filter capacitors.....and I have done that before on an older yet amp (no apparent capacity was left in those caps however).

I don't understand how to check the power supply voltage with the unit unplugged.

I hope I don't burden anyone too much and thanks in advance for advice.
250 watt stereo carver amp.

I'm not sure where to start.

Symptoms, turn on amp....hum.....meter jumps to 30watt output, then a click sound and then a burnt smell.

Open amp and can see nothing burnt looking. Fuse is blown ...
