I thought of that too, but I've read that Silpads aren't as good (thermal conductivity) as Mica/compound. I do agree they are easier to use. Of course there are many factors in how good something conducts thermally. Surface finish of both parts is a big one. Torque of the hold-down fasteners is...

Okay, great. I'll order a dozen of the MJ21196G's. I'll also replace the mica's and re-grease while I'm in there. Thank you!

I'd like to change the outputs on my amp to the MJ21196G's, since they are currently all original. The amp is still the factory quasi-complimentary design. I've read conflicting stories. Some say to keep the original drivers, and some say to replace everything with the MJ21196G's. Do they have...

Wow!

Agreed…

I’m currently running them with an Adcom 5400, and they need a little more power I’ve been watching the auction site, and there are some sheet metal fan shrouds available. Someone is actually remaking new ones. That will be a good use for the FLIR camera I’ve been testing the 400 on my A7’s...

I successfully replaced the bias transistors last night, and installed them this morning (along with the White Oaks driver board). No smoke, so that’s good Worked perfectly after I fixed the left channel input wiring boo-boo I made (minor). Sounds a lot quieter than the original board...

Thank you. I did catch that. The 2N5088's I have are different from the factory 2N3403's that are currently in-place. I de-soldered all the connections to the factory driver board last night and installed ferrules on the wires. I bought the connectors with the new board, so I like using...

Well, I haven't moved anything, all factory wiring placement. I only re-did the grounding around the input-output jacks to get rid of the ground loop issue (the jumper between the speaker jack and the input jacks). I also ran a new ground wire from the old driver board to the PSU copper buss...

Okay, thanks for the clarification. Hopefully I'll get my freshly built White Oaks driver board in this weekend! I'm looking forward to hearing it. Maybe the amp will be quieter with this board.

I'm doing this right now, and in post #20, the attachment say's to match the 2N5088's. I'm just looking for clarification before I epoxy the transistors into the metal loops. Nice write-up BTW, thanks! Bias transistors

I dont think I’ll ever get rid of my Akai GX-F66RC. It‘s just too sexy looking :) and it sounds good! Not my picture, I have the wood case on mine.

Thank you. do these need to be matched for Hfe? BTW: It took me only about 10 minutes to put your cap kit in on Sunday!

Thanks for that! I can definitely change them out of the metal loops. What's the advantage of the 2N5088 over the 2N3405? Some higher ratings I assume?

One of my bias transistors (the ones in the metal loop mounted to the chassis) came out of the metal loop. These: I put some thermal compound on it and slid it back in. Since I'm going to be changing the driver board to the White Oak board soon, I think I'd like to change both of them out. What...

From the horses mouth ^^

Pink Floyd live at Wembley, 1974 One of my favorite live Floyd concerts!

I’m glad I waited until after Christmas to buy this, the new version has a few more features that are really useful.

Yeah, I knew that was coming I didn’t have time to snap a picture last night. Standby…
