One chassis is almost ready... It is a nightmare doing metal works using only hand tools seating on the kitchen floor. I promise myself: No DIY chassis for my next Pass amp! :-)

P.s. It will look better in the end, do not judge now ;-)

Oooh!! Very nice chassis! Can you show any more photos? And perhaps with a CD or something similar for scale?

Hello

You`ve said 6L6, Zen Mod, Jacco Vermeulen and Nelson Pass converted me to make an Aleph 60.

What was so interesting / good at the aleph 60 that you prefer it?

I also think about to build the aleph 60 but have also another candidate.
The BurningAmp1.
But i have no idea what will be the main difference (soundwise) between this two amps.

In the past i also build an Aleph J which is a direkt successor of the aleph 30 so all the same Family.
Could it be that the sound of the Aleph 60 is in the same direction as the aleph J but with more power?
I have only Parts for 1 Amp left and have to make a decision maybe its easyer with help

many Thanks

greets alex

Here is a thread about Aleph 5 for reference(I can delete it after):Yet another Aleph 5.

These are what I have:
1) Chassis: 2 monoblocks with(per each): 2x 210mmX300mmX40mm 0.2c/w heatsinks, 0.19(~5mm) face, 0.125(~3mm) back, top and bottom.

(Will assemble and upload photos soon, waiting for some screws from "online").

2) PSU: 600VA, 25V 2x12A toroidals and 4/ch 100k uf 50v United Chemicon caps.

3) BrianGT aleph boards(photo bellow).

I will be using ZVP3310 as inputs and IRFP240 as outputs, which I will order(as soon as he has them in stock) form other forum member h-a.

Right now I have couple of questions which stops me and would really appreciate your help:
1) Which wires should I use for high current(non signal) purpose? Will any (from let say ebay) 12-14awg with teflon insulation work or you can recommend something better?

2) and major. I have an pdf(sorry can't upload excel, so include a link on it) file attached with schematics, board layout and parts number for the boards I have. I've tried to match parts number from this list to original schematics, but still have many gaps. I would appreciate if you be so kind to help me with this, because I can't proceed without knowing this correspondence. Please! :-)

Thank you in advance!
