hey gotta live right,lol
Is the D connected at the right place I would think it would connect to the gates?

Thanks!!!!!!

 

[Zen Mod]

D means Drive , and it's drawn on exactly right place



(don't try Truck-drive there )

 

[Botte]

That drawing is wrong. It's missing the connections from the gates. See

What he said!

There is a direct connection from D to the gate of Q102, and there is an AC coupled connection from D to the gate of Q101 through C101. Remember that there is a fixed DC voltage across Q113.

Am I missing something?

In the DWG of post #312 these connections were mistakenly omitted

Aha! Thank you.

Gee I have found so many different drawings ,boms and boards, I ordered the boards from the store,got 2 BA-GS v2.0 and 4 P-BASO-2V220,parts on the schematic in dashed boxes aren't on the board so I'll make a pref board for them,and 4 power supplies and it should be a go!
