Important detail.
Tommorow I will order the boards and the transformers. The turn around time on boards is 2-3 weeks till I see them, then I take up to a few days to ship them out ( assuming a weekend).
The factor that is unknown to me, and doesn't affect you , is how long the edcor transformers will take to show up. They say up to six weeks, so I hope it takes less, but assuming it takes six weeks since I will be ordering close to 100 units.
I have been building a few tube amps lately buying the trans from Edcor. The time has been 2 to 4 weeks before shipping but of course it could take longer as they say. I have heard of even 8 weeks but 3 weeks has been the norm for me.

For a while there, I think they were ahead on the transformer for the M-2. I got mine real fast, about a week if I remember correctly. Dont know if they are still in stock like they were but I got the feeling they were getting lots of inquiries on it and got ahead of the curve. Tea, You may want to give them a call and let them know what's getting ready to go down!
I've got everything coming from this group buy as well, next M-2 I think I might try the Toshiba mosfets, I have a couple sets around here somewhere from F-5 days.

Not any noise at all, even with horns. CL-60 to ground on chassis, ground on IEC plug/fuse/switch to same spot. Rca and speaker posts float of course. Most of these firstwatt amps are very similar. Member 6L6 has build guides for F-5, F-6 AlephJ and BA-3 amp. Do it just like he does. Every piece of Pass stuff I have including the preamps and Pearl 2 Phono pre are DEAD quiet. Nothing. NADA.Hi Russellc,
Any noise or low level hum from your build? How do you wire your ground?

When I did not use shielded input wire I had hum, if the signal wire actually got to close to the edcor transformer (not so much the AC power transformer).
You will note that Nelson used a top shield on his. I did not find it necessary, or notice a difference when they were on. I have left standoff screws in place however to put on on top, or levitate a alien input transformer with a different pinout instead.
Do you by chance have 2SK170BL / 2SJ74BLs available? If not, does anyone have a recommended source for them? Also, do they need to be match and across the N/P channels?

I used 2 short sections of Silver Sonic BL-2 interconnect cable. It is shielded and no hum. Transformers are un shielded nude in all their glory.

Can a particular IDSS be requested?

Hello Tea bag,
i just fall on you GB, am I too late ?
if possible can count me for :
- 1 pair M-2 boards
- 1 pair edcor transformers
- 2 power supply boards
- set of fets
i will PM my info for payment!
thanks!
I sent a PM to you yesterday, waiting for a response. I need you to PM an email address to move forward.
Off Topic and apologies.
I have a need for mono-bloc construction (probably with external PS.)
There was a rumour that the Shop may be stocking pre-drilled heatsinks, so in an attempt to hurry this along, I started a thread to gauge interest.
If you feel that you would rather build your own case/s but have the option to be able to buy suitable pre-drilled & tapped heatsinks please have a look at:

Here is what I ordered for parts.

Tea-Bag,
Do you have a pic of one of your stuffed boards? I'm ordering parts and I'd like to see how you did the bypass caps for one thing.
Thanks,
Jim
But if you want to see boards fully, I can try to get a good shot.
Are the you tube videos yours? They are good enough for me.
Jim
Yes, those are mine.
HI Tea-Bag thanks ,will be better as in ZM post that means R4 to 5R or better put a trim pot P3 like ?JFET IDSS would be good ~8ma for each option.
