Is a TO bigger than a TO? Share This Page Tweet. Do you see any gain numbers on any of those parts? Have also attached a scan of the power amp schematic. Your name or email address: Yea GR it looks like. I would like to replace all of the transistors on the power amp board. I datahseet appreciate your taking the time to help me with this.

I bought a rather hacked KR with blown outputs on the left channel. The a also says “5E C4”. 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. Am i correct in assuming “2s” should be in front of those? What part is on the messed up board? I don’t feel very confident about my sub for Qe19,20 – there is no datasheet datashdet.


The a also says “GR 5K”.

This package is a TO and the other one has a TO Thank you very much for any help on this! The other one has the wrong pin out. Lots of room for those. You must log in or sign up to reply here. Discussion in ‘ DIY ‘ started by gort69Jan 11, You have Qe 7,8 as 2sa but daatsheet the schematic it says 2sa WB. Log in or Sign up. You want to use the dattasheet pairs listed on the datasheet. Since this board has been messed with so much, I pulled the power amp from another KR I have that is unmolested, and listed here what is actually installed on the board.

There are some odd things on your list. Yeah, that’s a reason I I’m looking at the other board. No, create an account now. Curious what you think about my selection on those. Here are the datasheets for the outputs.

Can you determine if Qe 7,8 have the collector or the base at the center pin. Do you already have an account?

Are those Qe the drivers? Those two datashwet simply have “A” printed on them – I’m assuming they are 2sa 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. 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 dattasheet, or comment otherwise. Qe 2sa are your differential pairs.

I asked a question about the outputs earlier today. Per datasheets available online they are both center collector 2sa http: On the board I’m working on, Qe7 says a and Qe8 says a and both are very obvious poorly done replacements. SoundOfSoundJan 11, You need the collector in the center.

Yes, my password is: I was wondering if someone would bring that up. I’m getting conflicting information about a replacement. Yes, 2s There are replacements but you have to be sure if the center is a base or a collector. Are there any markings that tell the gain of the part that you can read? As you can tell I’m new to this.

I can order the caps myself, but need datasueet help with the transistors.

My understanding is that Kenwood and likely others used what they could get their hands on at the time.
