The a also says “5E C4”.

I was 2da872 if someone would bring that up. Yes, my password is: I asked a question about the outputs earlier today.

The other one has the wrong pin out.

You need the collector in the center. You must log in or sign up to reply here. Your name or email address: Here are the datasheets for the outputs.

Silicon PNP Epitaxial

You want to use the complementary pairs listed on the datasheet. Yeah, that’s a reason I I’m looking at the other board. Do you see any gain numbers on any of those parts? Are those Qe the drivers? On the board I’m working on, Qe7 says a and Qe8 says a and both are very obvious poorly done replacements. I really appreciate your taking the time to help me with this.


Can you determine if Qe 7,8 have the collector or the base at the center pin. This package is a TO and the other one has a TO I have spent a fair amount of datasheeet searching the forum for subs, but am hoping someone can look over my list and point out errors, make better recommendations, or comment otherwise.

Is a TO bigger than a TO?

2SA – 2SA PNP Low Frequency Transistor

I would like to replace all of the transistors on the power amp board. Lots of room for those. SoundOfSoundJan 11, Log in or Sign up. The a also says “GR 5K”.

Have also attached a scan of the power amp schematic.

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.

What datahseet is on the messed up board? You have Qe 7,8 as 2sa but on the schematic it says 2sa WB. I bought a rather hacked KR with blown outputs on the left channel.


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. Thank you very much for any help on this! Yea GR it looks like. Discussion in ‘ DIY ‘ started by gort69Jan 11, There are some odd things on your list. Do you already have an account?

I don’t feel very confident about my sub for Qe19,20 – there is no datasheet available.
