2SC4388 and 2SA1673 replacements?
- Thread starter spooney
- Start date
As pricey as these are I have found no useful replacement for them. I just get the client to help me bit the bullet at PCP and use the original pert. I believe these were LAPT transistors and so they were designed specifically for audio application.
Linear Audio Power Transistors = LAPT
If you ever do find a US replacement LMK I would be extremely interested in testing your find...

bdent.com has them for 3.89 a piece for the 2SC4388 and 4.21 a piece for the 2SA1673. Minimum order is 15 dollars which isn't horrible. Just not sure how reliable of a supplier bdent.com is. The only other place i have seen them is at mcm electronics for 7+ dollars a piece. I'll have to see if the owner wants to spend the money to fix it.
www.pacificsemi.com has them, 2SC4388 $1.91 and 2SA1673 $2.59, there in the US too so shipping wont be too bad and the minimum is $25 which isn't too bad, (just make sure they say origial or you could get fakes).

This amp only has one of each for a channel, so it was $8 for those. I needed other stuff, so for about a $30 order it shows $6.25 shipping at B&D. This amp, same deal not worth much of anything but it says 600 watts on the front....must mean something. I think it is 100wrms x2, not bad for a high side application or small sub. What, $30-40?
I think it is 100wrms x2, not bad for a high side application or small sub. What, $30-40?Ok, forgot I ordered some 2sa1694 from a place on ebay in the UK. They came today and look nice, but they are ISC brand. All I find is this: http://www.diyaudio.com/forums/showthread.php?threadid=115281
So ISC must be legit manufacturer? They were cheap like $16 shipped for 4 thought I would test them in an audiobahn that is a little rough anyway. Can't anyone stock some Sanken in the US??? I see lots of them. Oh yeah, you don't want to stock anything I forgot...JIT...

Its an 800wrms amp, I can't power it up enough to clip it not even close. My 4 IB 12s in the car can't take that much either, maybe 600rms according to ratings though my 420w does not do much for them xmax wise.

Still cheaper here if you request the $10 flat rate shipping

www.pacificsemi.com has them, 2SC4388 $1.91 and 2SA1673 $2.59, there in the US too so shipping wont be too bad and the minimum is $25 which isn't too bad.
Correction: they are in Canada but $10 flat rate shipping is not bad.
