Got some hetefor that very purpose, but my rope is even longer. So you think you need voltage gain cause of low gain. I want to try laterals too. I like them a lot.

frankly - I don't need more amps - (almost) everything is good enough , while music matters most

but , parts are what's urging me to make amps

Just enjoying the F6

When Tea Bags boards are available will try to compare the Jensens to the Onetics that are currently installed

Maybe somebody will release other SITs in the next year or two

Best
Bob

I have been playing with F6 Degeneration and distortion (which goes higher when trying to maximize 2nd harmonic in my guess) and then trying to evaluate the sound to my ears. It certainly changes the sound. Darker I think.

Trying to rest more, lots of virus activity here in US and New England.
I really don't want that, after already recovering from something.

The VFET idea sounds great. I would try that if Acroman's parts would work. I've been evaluating Mike R's amp too.

On the list is matching some SemiSouthFan's parts.

Some people have been really helpful in all this - They should be mentioned.
Generg, Flochini and Buzzforb. Keeping me on middle path.
Tea-Bag needs counselors to keep his progress going when ideas become stronger than action.

The onetics was sharp to my ears, but when adjusted for second seemed to blend really well into nice mixture. Try it out.

I spend (waste) 2 hours a day reading all the threads I am interested in, should be building something. I do listen to my lovely system while reading, so all s not lost.

I hope that you all will have a safe, prosperous and healthy 2013. Zen Mod. Please show a proposed schematic with focus on biasing.
Best regards.

You can connect the gates to same biasing scheme as original, just swap points.
