Cheers, but their 12fk6's are $7.95 each

Ive sent a message to another tube store, totally forgotten their name but they have a red background on their website and only sell tubes (no accessories).



Thats alot of money for some, but I enjoy the sound so much, that it almost seems worth it.

c0ns, sounds cool. I think I'd just need something like DAC/RCA. would be cool to find maybe a good switching mini jack kind of like the neutrik 1/4'th we use cause I sometimes use mini-minis. I had some ideas bout having the 5v from usb feed a gate that switches a relay.. anyway, keep me updated

btw, where are there the gold plated neutrik 1/4'th input switching jacks? I've seen some in some builds or something..

Just need to confirm. I took a look at the KZ line and the next up would be the 50V, 1000uF. So I should swap out the current ones for these?

1st - This is only conjecture. I can't guarantee it will make a difference.
2nd - Remember that these caps are CA4L/R and CA5L/R. Those are plain old power caps all the way. So, Panasonic FM's will have better performance, but again - it's up to you. They also only need to be 35V.

The reason there are four pins switching is so that you can just use two if you want.

I haven't looked closely enough at the relays yet, but I think I can probably make it so you can drop in DPST relays if you are only going to be switching two lines.

If things go as I hope, the cost from me for PCB + IC will be something like $10. Or you can just etch your own board and run the IC on that.

This is all still in the planning phases, of course... More will be known after I get the software finished. (I haven't started yet, but I figure it's a day or so to get the basics down, then a bit of polishing.)

Test etch on the photo mask for the experimental MAX went well. Picture not so good.:wink:

Its ALIVE....!

First of two Millet MAX builds is up, biased and running smoothly. Flipped the switch and it came up smoothly with no problems.

Adjusted PS output level to 27V checking to make sure that DB bias current wasn't off the wall. Biased tubes 13.5V.
Then adjusted DB bias up in stages to current 105mV (50mA) for burn-in and to stabilize.

Fitted with FM7's. The DB QA8/QA9 are the 2SA1011/2SC2344 Sanyo BJT pairs.
ICW Clarity SA 0.47uF 630V Film Caps are Tombstoned into the CA7 & CA8 positions for a little uniqueness. Not quite up to par with Ferrari's
HYPER build levels... but a little different personality

All I’ve got to say at this point is WOWWWWWWWWWWWW.......

And this is only with a couple of hours on the Caps and those NOS FM7’s. This thing is going to kick some kind of TAIL when it is fully burned in!

Will try to post up some Pics soon.
