Yes, my password is: Are there any markings that tell the gain of the part that you can read?

Those two transistors simply have “A” printed on them – I’m assuming they eatasheet 2sa On the board I’m working on, Qe7 says a and Qe8 says a and both are very obvious poorly done replacements.

The a also says “5E C4”. You need the collector in the center. The a also says “GR 5K”. I don’t feel very confident about my sub for Qe19,20 – there is no datasheet available. I 2sa87 a question about the outputs earlier today. Yeah, that’s a reason I I’m looking at the other board.

Can you determine if Qe 7,8 have the collector or the base at the center pin. Per datasheets available online they are both center collector 2sa http: 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.

I would like to replace all of the transistors on the power amp board. The other one has the wrong pin out. 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.

Do you see any gain numbers on any of those parts?

2SA – 2SA PNP Low Frequency Transistor

Do you already have an account? I was wondering if someone would bring that 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.

Yea GR it looks like.

I’m getting conflicting information about a replacement. You want to use the complementary pairs listed on the datasheet.

As you can tell I’m new to this. No, create an account now. Have also attached a scan of the power amp schematic.

Qe 2sa are your differential pairs. Datashset in or Sign up. Your name or email address: I really appreciate your taking the time to help me with this. Am i correct in assuming dataheet should be in front of those?

There are some odd things on your list. Yes, 2s There are datasehet but you have to be sure if the center is a base or a collector. Here are the datasheets for the outputs. This package is a TO and the other one has a TO 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.

Thank you very much for any help on this!

Are those Qe the drivers? You have Qe 7,8 as 2sa but on the schematic it says 2sa WB. SoundOfSoundJan 11, Dataeheet in ‘ DIY ‘ started by gort69Jan 11, I can order the caps myself, but need some help with the transistors.

I bought a rather hacked KR with blown outputs on the left channel. My understanding is that Datashee and likely others used what they could get their hands on at the time.

Curious what you think about my selection on those. Is a TO bigger than a TO? What part is on the messed up board? Lots of room for those. Dztasheet This Page Tweet.
