Ready-to-Run (RTR) SSR DC Speaker Protection and Delay GB

[xrk971]

just ordered 4 boards in the shop. I had to reduce the number from 6 to 4 because I originally only wanted the empty boards....

thanks
Markus

Thanks, Markus!

Update on the status of production. The fabrication house is still waiting for the non polarized 220uF caps to arrive before assembly can start. Perhaps two back to back polars would be easier to procure next time. They take more real estate though.

Thanks for your patience.

I like the use of the Opto for DC detection and good selection of SSR. I bought 2 boards yesterday. Thanks X!

Thanks, Fab! Is this going onto the USSA5?

Vunce, Zman01, and myself are about to have a USSA5 build party. We have all been collecting parts for a few years now.

Hi X
My USSA5 already has DC protection but with relays. I will use the new SSR protection for my next amp. Thanks for doing this group buy.

Looking forward to seeing progress on your amps.

Status Update:

We are still waiting for the first verification unit to be sent to us. The manufacturing house had trouble finding some parts for the BOM, but that has since been resolved. Once we have the verification unit in hand and it is approved, it takes up to 3 weeks to have the whole batch to be produced.

Thank you for your patience. We did not expect it to take this long either.

Thanks for the order, Meanie!

48 units remaining.

Hi,
Is there an update?
Thank you.

 

[xrk971]

Hi Folks,
We have inquired with the board assembly house as of yesterday but have not heard back yet. Can only imagine they are building it but can’t understand why it’s taking so much longer than quoted time. Sorry for the delay and thank you for being so patient.
Cheers,
X

Just saying but I remember that I had once comments for the engineering department of a pcb manufacturer where it came through my junk emails box...

[xrk971]

Finally, we have an update from the manufacturing house. A sample of the SSR DC Protection has been built (see photo) and they are shipping to us for testing before commencing with the full production run.

 

[darrr]

Soldering does not look good. not enough adhesive on some pads.

 

[xrk971]

I guess we will have to wait and see it in person. But I do see that there is still some gold showing through on some of the pads.

 

[xrk971]

Great news folks: Jhofland has received the test unit from the manufacturing house and he tested successfully for DC protection, delay at turn-on, and it flowed 100w into 8ohms. We have asked them to begin production of the full run.

 

[gary s]

That is good news X.

I assume they have all parts in stock now that were delaying the prototype manufacture.

Have they indicated a lead time to supply the full run at this stage?

 

[xrk971]

Yes, they have all the parts now - that's how they were finally able to produce the single test unit. I would assume the PNP machines are all locked and loaded and ready to go. Probably within a week to complete the assembly, if not days.

 

[darrr]

What about soldering?
