[Algar_emi]

Corrected BOM, thanks for the info. That's what happen when you maintained different version of a BOM. If I'll resend the corrected BOM to all GB members.

Received my 5 extra pcb, so I still have a few to sale.

Thanks

A little preview of my build.

Waiting for some RCA sockets as I ran out so I haven't heard the magic yet.. although it fires up without smoke

Chassis front was done on my homebuilt CNC and I have made a windowed top cover in white+clear acrylic. Not sure if it'll look good or not yet..

I ended up cutting the track by the 24v insertion point so that I could switch off the DC side. The resulting connection isn't as pretty as I'd like, so I might revisit that later and bond a new pad where I made the hole in the PCB.

Very nice

Just 2 pcb left of the last small batch of 5 I ordered. Your last chance to get one...

My board seems to have disappeared into the ether. Given up hope of it ever arriving

 

[Algar_emi]

Someone in Germany just received it last week. Seems to take some time, maybe the dissaperance of the Boeing MAX738 fleet did some effects on the air cargo deleivery as well...

Someone asked me for the pcb holes location. I made the pdf with the dimensions. If you need it let me know...

If I were to use the 2SK170 option,
May I know what IDSS range should I target to purchase?
Thanks.

Hi. Just sold my last pcb. Don't worry I often order pcb, so if by the end someone didn,t get his pcb, I'll place an other small order.

Thanks to all

Hello,
Could I get a bit of advice on wiring an Alps pot to this wonderful pcb? I bought the pot with a nice little pcb to aid wiring. Just not sure how to connect to the 2 sets of 3 pads on the amp board. So far I get the left right bit
Thanks!

 

[avtech]

Should be something like this (I think..)

 

[Roo2]

Thanks for that avtech23. Tempting to wire direct (without the extra pcb) per your extra image to slightly simplify the signal path..

Will be looking forward to build this one
Again..... big thanks

Having checked that the p/s was giving 24V I installed all other components and now have a problem. I no longer get a stable 24V the reading fluctuating all over the place. The board has been cleaned and checked for solder bridges and bad joints; there are non. If I unsolder the 10R resistor the p/s gives a steady 24.04 vdc. No audio input or output connections are soldered. Any advice gratefully received bearing in mind my dire diagnostic skills.
