Folsom LOFI PCB's (Transformer board) & DC PCB's (PSU boards)

[Destroyer OS]

The DCS2 is revised, it had an error.

Everything is available.

Thanks Destroyer . i reveived your best remedy for the pcb

 

[AmpUtator]

If available I'll take 2x Lofi's and 2x DCS2's.


Thanks.

 

[Destroyer OS]

Yes, there are still boards. PM sent.

 

[AmpUtator]

If you can't wait for replacement, then here is the orientation you can use.

Received my boards today. Thank you.


Have a look at the cap orientation on my DCS2 boards.

Mine appear to be different from the above orientation.


If I need to re-orientate caps a simple drawing posted will be fine.


Thanks again.

 

[Destroyer OS]

Yours is a corrected board. Follow the board.

 

[AmpUtator]

Great, Will do. Thanks.

Please forgive the NooB questions. Am I correct that I would need 1 LOFI board and either DCS1 OR DCS2 (separately purchase all the components, resistors, diodes, transformers etc...) to complete 1 mono amp?

What’s the significance of “Folsom” in the title?

Perhaps a fan of Johnny Cash

Who isn’t!

I ask because I live within earshot of the shift change sirens at Folsom Prison. Curious if I have a DIYAudio neighbor.

Yes, but I have no idea what amp so I can't say if it's big enough (the transformer is only 48va).

What’s the significance of “Folsom” in the title?

Company name. It's also my middle name.

Neither of us own any music by him, actually. And neither of us have been to prison.

Hi, just trying to get a good feel for the best direction to take in order to get the best possible components built for my first diy attempt building 7293 mono blocks.

Do the LOFI/DSC replace the dualpole PSU for use with the 7293?

If so, what improvements can be expected?

Thanks,

Jody

 

[givemeyoursoul]

Are these still available? If so, how do I purchase a couple?

No, the DSC and LOFI boards are only for smaller power items such as DAC's and phono stages.

Sorry for the very late reply but I didn't get an email notification for whatever reason.

While waiting for the amp boards to arrive and hence the order to Mouser, etc could I possibly use a Schaffner RN152-8-02 common mode choke on the power supply filter boards that arrived today (thank you very much) instead of the recommended Coilcraft P3717 - the pins will need to be extended etc but as I have a couple here, wondered if they'd do the same/similar job?

Another couple sitting here too are the Epcos B82725-2103 - altho the pinsare nowhere near the pcb holes, they could be extended to fit if they're suitable here - perhaps the other components would need to change?

 

[Destroyer OS]

You can use those but I can't guarantee optimal performance along with resistors values.

 

[jameshillj]

Okay, thanks - will give this board 'a try' and add correct chokes with next parts order with the amp boards

Hi. Are these still available? I believe I would be after an LOFI and a couple of DCS1s.
