Upgraded Single Board PCM1794 NOS DDDAC

Hi Juanco,

I just re-check and in your request is not included the soldering of the SMD parts for the Buffer.

You request to have 1/2 clock delay with SMD parts included and soldered. This parts are not from carlsors.

Maybe I miss something?

Regards,
Enrico

Hi Enrico,
I probably got confused with all the options and for some reason my name kept dropping off! I asked Carlsor to send you my buffer parts so can you solder these and I will pay you any cost difference!
Thanks

Hi David,

No problem. The cost for the solder SMD parts for the Buffer is 12 USD.

I will put you apart waiting for parts from carlsors.

Best Regards,

Hi Enrico,

please send my boards directly.

When you reminded me that it would take 3/4 weeks just for the parts comming to korea,
I decided to try the soldering by myself.
So I think, I should not be on the list any more (maybe kept the place of juancho?) :confused:.
Sorry if I caused any confusion.

Best regards

Hi Torsten,

No problem at all.. I will refund you 12 USD and I will send your boards tomorrow morning.

Korea Post prices

Dear All,

This morning I send the boards to all of you with the exception of the ones that requested me to solder the buffer parts. Tomorrow morning I will send the ones for titus2002 and tods.

:eek: I am embarrassed... It seems my korean is really poor and I completely misinterpreted the printout of items Korean (anyway, really difficult to interpret) and the cost of regular shipments. The prices that they give me when I asked was referring to boxes and not envelops... So the price that I asked you is completely wrong!!

Please accept my apology and a refund of $ 5 to each of you that I will send tonight when I back home.

I'm sorry for what happened... my bad :(

Regards,
Enrico

No need for apology, that's a nice little bonus for everyone.
Thanks again for organising this Enrico :)

TOP TOP man! Really a big thank you for all the effort and this amazing GB.

Refund was a bonus and I would have stated to keep it as a thank you :D
 
Susumu Rload Resistors Pictures

IMO it is important to upgrade the RLoad resistors above the stock Dale RN's. The TX2575 z-foils and Rhopoints are reported to be the best, but are expensive and 133ohms are special order. The Tantalums are a more reasonable priced upgrade but the closest I was able to get was 2X270ohms. The Susumu RG SMD transistors have greater clarity than the Dale RN's and sound at least as good as the Tantalums to me.

What I can do is provide ten 0.1% 270ohm SMD Susumu 1206 RG resistors plus a 2cm X 4cm piece of adhesive backed tinned copper sheeting for SMD installation for $8 plus shipping in an envelope. No extra shipping if mailed with other parts order. Paralleling 270 ohm resistors provides 135 ohms for a single board DAC. The large Susumu RG is not available in 133 ohms, but this difference should not be audible. The purist can add a 3rd 10K resistor in parallel to get 133.2 ohms. Four 10K SMD resistors add $3 to the price. For 2 Board DACs needing 66-67 ohms - three 200 ohm SMDs in parallel equal 66.7 ohms. Cost for 14 0.1% 200 ohm Susumu's and copper sheeting piece is $11 plus shipping. The wattage load for a 4+ board DAC is too much for SMD resistors. PM or email me if interested.

Attached is a picture of the Susumu RG resistors installed in the Rload position using the adhesive backed tinned copper sheeting. Both sides measure 134.9 ohms which should minimize DC offset. There is room for 3 SMD resistors in parallel if needed. Looks more secure than using wires to bridge the gaps.

GB SMD Parts Status

All of the 2SK208 JFETS for the CCS boards have been tested. SMD parts kits have been mailed to 5 persons who only ordered CCS boards. The CCS SMD parts kits will be mailed to the remaining CCS boards only persons tomorrow.

I have tested 100 of the 400 BF862 buffer JFETS and expect to be done testing in about a week. They will be sorted into matched sets and mailed as soon as possible after testing is completed.

I will notify each person when their SMD parts kits are in the mail.
