I really appreciate your taking the time to help me with this. I have spent a fair amount of time searching the forum for subs, but am hoping someone can look over my list and point out errors, make better recommendations, or comment otherwise. The other one has the wrong pin out. No, create an account now. I’m also hoping someone can point out which are the differential pairs so that I can order a bunch of them to match them up.
Transistor Sub Help Please – Kenwood KR-7600
Discussion in ‘ DIY ‘ started by gort69Jan 11, Have also attached a scan of the power amp schematic. Per datasheets available online they are both center collector 2sa http: I’m getting conflicting information about a replacement. What part is on the messed up board? You need the collector in the center. I was wondering if someone would bring that up. You must log in or sign up to reply here. Here are the datasheets for the outputs. Yes, my password is: On the board I’m working on, Qe7 says a and Qe8 says a and both are very obvious poorly done replacements.
There are some odd things on your list. My understanding is that Kenwood and likely others used what they could get their hands on at the time. I would like to replace all of the transistors on the power amp board.
Are those Qe the drivers? Yes, 2s There are replacements but you have to be sure if the center is a base or a collector. You want to use the complementary pairs listed on the datasheet. I bought a rather hacked KR with blown outputs on the left channel. Those two transistors simply have “A” printed on them – I’m assuming they are 2sa Qe 2sa are your differential pairs.
Do you see any gain numbers on any of those parts? Log in or Sign up. A previous owner has butchered this thing badly picture attached with all sorts of oddball replacements and beautiful soldering, so I would like to start over.
Can you determine if Qe 7,8 have the collector or the base at the center pin. Lots of room for those.

I can order the caps myself, but need some help with the transistors. As you can tell I’m new to this. I asked a question about the outputs earlier today. Your name or email address: This package is a TO and the other one has a TO Is a TO bigger than a TO?

The a also says “5E C4”. I don’t feel very confident about my sub for Qe19,20 – there is no datasheet available.
Yea GR it looks like.
Share This Page Tweet. SoundOfSoundJan 11, Am i correct in assuming “2s” should be in front of those? Yeah, that’s a reason I I’m looking at the other board.
