Hi Peter,
I have mailed you some time ago - round Dec 2005 regarding pcb for A30 and....:/
Anyway - I am still into buy of pair for A30 - please let me know if there are some left.
Thx in advance!!!

I see the light...
Now that I understand my error, which means I can afford the stock aleph power supply, I'll just stick with what's on the schematic. Ok, I'll spring for three times the capacitance. At least I won't have to take out a second mortgage to pay for them.
Thanks for responding, folks.

So, in a coincidence with this second run, I just powered up my PDA30s from the first run. I am using the BrianGT Power Supply board with them, and running twin 350VA 16V trafos. Sounds great, and keeps me warm in the snow...
Congrats🙂 Is this your first Pass amp? I remember clearly when I connected the first BosoZ to my system, what a glorious day🙂
My whole system just sounded so much better🙂
Any chance you have a pic to share, Brian?

Hi Peter,
I have sent message from your web page - please let me know if received.
Thank you.

Soon. Right now it's just sitting in parts on the workbench, but I have all the chassis bits ready, minus some wood panels I need to mill out of Walnut (have the stock for that too). I am pretty swamped with the X-BoSoZ kits right now, but maybe next week I'll see some daylight.
PS: For the chassis, I am using an old Antec Aria aluminum frame and heatsinks I got from mpmarino.
PPS: Peter, do you have pics of the completed "Aleph Vesuvius?"
It could be, with some additional cover panels.
But I'm thinking about using it for Aleph X amp, where two A30 boards are mounted on each heatsink (and used for output stages only) and the input stage wired separately.

zen version 3 power supply
Hi everyone,
Nelson demonstrated how to construct a regulated power supply for the zen-3. I want to use it with the aleph 30. My question: do I use this ps after the aleph's ps capacitors, or does it eliminate the ps 10000uF caps altogether?
Thanks,
John Inlow

Re: zen version 3 power supply
I received all the boards today and will be shipping them tomorrow. For Europe, you may expect delivery middle of next week, for USA it's really hard to say, it may be 5-10 days, depending on location
I'm not familiar with that PS arrangement, but why don't you use same caps values as in Zen-3 with reg supply. Usually, with regulated supply, lower capacitance is needed, comparing to unregulated supply.

Thanks Peter! I will post when mine arrive..... That should give you a good idea of the amount of shipping time to this part of the globe!

received boards
The boards were sitting in my letter box when I arrived home this evening. 3 days from Canada to the UK is very impressive 😀
Very nice looking boards Peter, thank you

Input cap
Has anyone tried 10V rated Sanyo Oscons as the input cap C11?
I need to order some more 220uf caps and think these may be worth a try.

The boards arrived in the mail today in Minnesota. The quality of the boards is excellent! Thanks Peter.
My boards arrive today. They look excellent. Thank-you!
Question: are the 2 lines in the underside of the board
where jumpers go?

Yes, the lines are for jumpers, but they don't neccessary need to be installed. I posted detailed info here: http://www.diyaudio.com/forums/showthread.php?postid=617068#post617068
Aleph 30
Peter
thanks for the email.
I notice on the photos of your populated board that C7 and C8 are missing. Is it that they hadn't been fitted at that time, or do you consider them as not needed?
Do you know if C11 could be bypassed with any benefit, or could it become unstable or something?
Do you have any of the 0R47 3W resistors left, I didn't order enough
