Pavel Dudek's super Gainclone group buy

[bk856er]

Nice job! Great looking case. Where did you source it and what size is it?

Mine? Thanks!

Case came from the diyA store - awesome service and awesome case. These are the specs:

Galaxy 2U w/Aluminum Covers, 230x230mm size, optional fully vented top.

It's dense inside, so it's important to carefully layout.

OK, I'll go for a PCB. Not sure how I'm supposed to buy it though.

Do you know now? You click at the EDIT SECTION icon (link in my sig below) at the table and then edit or you send an email to me and tell how many boards you want.

Hi Per-Anders!
I'd like to buy 4 boards, please.
Thank you.

 

[peranders]

You have instructions in my signature.

 

[peranders]

10 more boards to get hold of but hurry up.

 

[SCarlsson]

Take 8 boards

Hi Per-Anders,

I take 8 boards if still available. Signed up on the wiki. Await invoice.

Regards,
Stefan

2 boards left for this time to order. I'll get the boards today I'll hope.

Bridged operation, differential in.

Hi!

Happily awaiting the PCBs, in the meantime, planning my build:

1.
I would like to build this PCB for bridged operation driven by one differential input. Would the attached connection be the way to go? Ground is audio ground, not pin 1 on XLR which goes to chassis ground.

An externally hosted image should be here but it was not working when we last tested it.

2.
I have a +/- 32 V PSU box. Could I power the gainclone from this instead of buying more transformers? Would I connect it directly to the big filter capacitors?

Best regards!

 

[peranders]

The connection according your picture is correct. You can of course connect DC. Please consult the schematics for this.

Thanks! This will be fun=)

I have a nice pile of green and golden pcb's.

 

[quantumQ]

Hi, I ordered a set of the boards. When can I expect delivery/

 

[peranders]

I will start the distribution of the boards earliest on Tuesday.

 

[peranders]

Shipping time is 2-4 days for Europe and 5-10 days to the rest of the world.

 

[quantumQ]

Thanks P-A I am looking forward to checking them out.

 

[peranders]

Some boards are shipped today.

 

[nthall]

Awesome. I'm really looking forward to see what these things can do.

peranders I am finally building the board (the red one)

Would you mind explain the large amount of parallel resistor installed at the output of the op amp and the ones at the bypass. Wouldn't they replace it with one high quality resistor even better (e.g caddock MP 0.1R )

Maybe here at #17?
