I had just written a long congratulatory reply here--- accidentally hit the wrong key and it went to vapor. Darn.
Allow me to again, however, extend my heartiest congratulations to you as the grand prize winner of the MagneQuest Craftsman's Room at VSAC 2008.
I heard through the grapevine much buzz about your amps. Everyone has spoken only with praise for the level of craft and design that your amps exhibited.
As usual, I am frequently behind in my email duties. And I apologize. However, I did send you a short email this morning providing you with contact info for myself and inviting you to call. If you miss me--- feel free to send me your phone contact info via email and a good time to call and I will ring you.
Grid chokes can work very well in 300B single ended circuits--- in several different spots potentially--- and then you want to pick the grid choke best optimized for the "position" in the circuit it occupies. We can help.
Also--- always feel free to post to our MQ forum here---- we have a host of very skilled designers and DIY'ers--- and generally you can get some good ideas or other input from this broader community of builders.
So cheers and congrats--- job well done.
