I have been out of the country for a few months and had not checked in for a long while. Just noticed that the SSHA kits were being offered. Is it too late to order one? Thank you!

Attached is a P-P wiring sketch I made a while back for my build, I've been ask many times for it.... so it's easier just to repost it.

Thanks alot for the quick response. I know it would have been a great exercise to try and wire it myself. But it's always alot easier when somebody has already made one. Thanks again.

Just an FYI to everyone about the custom Beezar/Hammond cases:

1. I'm ordering 50 cases tomorrow. Hopefully, the 6wks will start ticking from that point, but I'll let you know for sure.
2. Based on sales this weekend (and other factors) 30 kits are all I'm going to do. Right now, there are 12 left. A few people ordered just the cases themselves, but we're still quite aways off from 50 cases.
3. There is no profit for the cases at the price they're at right now - this is essentially the same as a group buy.
4. However - since Hammond allows us to add to the order, you will still have the next two weeks (till Monday, June 15th) to place a pre-order for a case (or the case+kit) at the current price.

It may be OK, but I bet you can find one that's absolutely identical and has all the right numbers:

They sent me a PM and it's clearly 48V output and 0.38A. So that's ok. Though is the plug itself ok? (was that what you were doubting about?)
Here is the plug of the adapter:

Thanks

EDIT: NEVER MIND, THE PLUG IS OK: 2.5/5.5 AS IT SCHOULD BE, SORRY FOR POSTING TO FAST
THANKS

hey tomb!

thanks for making the Millet SS available in pcb + tubes.... i've added all the caps i need, but i can't seem to find the resistors and transistors (q1 + 2) on your site? not there, or am i blind??

in any case, i'll still order - would be great to get em bundled with the pcb tho, as digi key and mouser charge $$ for shipping making that an uneconomical choice...

just thought since you offer full kits, maybe you have these available? if not yet, planning on doing so?

thanks!

joe

EDIT: We need to start asking these questions through PM's. Much of this is centered around the case, which we're treating as a Group Buy, figuratively and literally. However, some of the rest of this discussion is on the edge. Mods, please delete if necessary. Thanks.

Hey all

I replaced the c2 and c4 (539-150104K100AA
mouser) of the original BOM of pmillet by 2 of these: 598-WMF1P1K-F mouser
You think those will do?

 

[rshuck]

Hi tomb - I've ordered one of these as well (didn't see this thread at first, just your site). Can't wait for it to come in!

Thanks for making an easy solution available for this - it'll be my first tube amp aside from a Dynaco Stereo 70 I tried (and failed, horribly) to repair.

 

[PJPro]

Yeap. Me too. Full kit in black.

Yes they should work fine... however personally I'd use parts from tomb's SSMH BOM as substitutes if you cannot find those obsolete parts.

tomb, I just made an order for the tubes and board (but I ain't gonna use that) of your site. Very easy to order and I was surprised by the low delivery costs for shipment cost to europe. Class A purchase.

tubedepot asks 72 buck for 3 19J6 tubes!! (and shipment to belgium ofcourse)
I bought the board, tubes, and sockets for 32 dollars on beezar + shipment!!!

I don't know if I am allowed to tell this here, so plz delete if inappropriate.

You're allowed to post what you want, within reason. It's me as an MOT that has restrictions (like when someone posts, "How much?" and I answer.).

Is it possible to replace the mosfet stage with a gainclone to give it enough power to drive speakers? Sorry if its a silly question.

Not directly, since the quiescent current through MOSFET is recycled as heater current for the tube. However, if you provide extra heater power supply, you can certainly hook-up a power opamp ("gainclone") after the tube. Such ideas can be seen at diyaudio.com; Pete Millett also has a project like that, although that one is not the least complex one.

But what is the purpose of an extra tube gain stage in front of the gainclone? The chip itself can deliver all the gain you need. As a matter of fact, at least some of these chips are not supposed to be used at unity gain (as the MOSFET is in the "starving student")... from LM3886 datasheet: "LM3886 is designed to be stable when operated at a closed-loop gain of 10 or greater". So you would have 10 x gain of the tube, I don't know if you need that much. On the other hand, the chip-amp probably performs best if driven from low impedance, so perhaps a cathode follower (instead of common cathode gain stage) would have some benefits. Of course, that would not have anything in common with this "starving student" project to be made out of junk-box parts any more. But then again, the PCBs, custom ordered pre-drilled enclosures etc. discussed here don't either.
