I haven't built the F6 yet, the chassis is not quite done and still at the machinist...

The F4 is my favorite Pass amp so far, and by a wide margin. (But that is comparing Ferrari's, they are all wonderful...)

buzz really likes his F6, and I am very enthusiastc to give it a try.

But which is best? You have to build them all to find out.

I know I know

Just thinking out-loud

I guess it will be F6 for me first... but I really want to give F4 a try as well

Double SSLV BiBs powering BA3 on full dual mono and then driving F6 and/or F4 directly should be really interesting too

I just worry what coupling caps I will find to match the quality of the Russian FT3s on my DCB1...

valvesound -

I've run into bandwidth issues with the hosting site I use... I'm at the free limit and am not sure how I am going to proceed... Starting to pay for something has it's pitfalls as I would then have to pay indefinitely...

Anyway, the good news is that the Free limit is a monthly issue and will reset in a couple days (Anniversary of my joining day, not end of month, so it's an odd date...)

My suggestion is as follows;

Wait until you see everything again.
Save the page locally so you can view it off-line. -- This way you have it and are not at the mercy of photobucket.

I will do something in the near future to alleviate this problem. Probably a PDF and a re-make of the photo part of the thread and host all the photos locally. Like anything, it's going to take a bit of time.

6L6....a question on the components:

I see the caps (220uF) aren't noted on the BOM?
Where did you buy the 22.1 and 22.1k resistors from? Do they have to be X.1 or can I use 1% 22E and 22k instead?

Thanks

I looked in the diy store and did not see the power supply board where does one find it? Is there a generated parts list any where?

22R and 22K are perfect

Tx ZM.....i guessed that X.1 was specified to force 1% tolerances.
