So, here I go. Phase Linear 400

Well, I did. Navlinear 3 d printed those at one time before the Whiteoak back planes came around. You can certainly PM him to see if he has any left. When I get home I'll check my stash...
 
Lee I was just shitting around with you....I wanted to think I was the one and only anointed one to receive such gifts you know....:king:
 
Out of all I should have known. It's bad ass to know that parts can be made on a 3D printer.
 
I've successfully used Onsemi MJF15030's for the Q6 transistors in the bias circuit. The nice thing with this transistor is it's a TO220 in an isolated tab. It mounts perfect on stock amps. There is an added benefit. The fans typically found on computer cases have a connector with the same spacing (.100") as the transistor. If the fan cable is cut off the fan, the connector fits perfect on the TO220 leads and eliminates the need to solder leads on to the transistor. The down side to this is the TO220 does not fit in the space allotted for the White Oak backplanes.
 
Thanks Don that is pretty crafty. Do you use a silipad/thermal pad behind the transistor ? Mine came out great !

The only benefit to silpads is electrical isolation which the MJF15030 providees. My testing indicated thermal tracking was not an issue. What I really like is the improved reliability of the TO220 leads.
 
At 8 amp, 120-150v, 50 watts that joker oughta Cadillac right along for a great long while !
 
Thanks VSAT88 for asking the group. Too bad they cant be seen with the amp put back together.

Just wanted to thank Joe who helped me a bunch and thanks to all the posts from these forums. Just got my garage sale amp back together and enjoying it. Also, thank you Mark for your YouTube videos.

oooooooHHH Gold plated phono/RCA's . Shit, I wish I had bought those instead. They look good. The whole amp looks great.
