Ultlimate Ver.2 Twins TDA1541a Non-oversampling DAC Funish products..................
Hi All,
I received the funish TDA1541a kits already.
although factory test already, I still need to spend 12 hours to running for them( everyone ) for the stability or not.
Kits supply to Market will 2005-04-22. (Friday)
This is every kits contain.
PCB
-----
4( Four ) pieces of Plasma Spark shine Blue colour PCB.
Two will all factory funish & two will Blank.
1. Twin TDA1541a PCB fully funish & test already.
Parts- Diode was Vishay -telefunken BYV-27-150
(Ultra-fast soft receovery diodes)
REGULATOR ICs LT1033 & 1057.
TDA1541a Decoupling caps was ERO MKP1813.
Extra 28 pcs 1541a decoupling caps Philips Holland MKT will follow with kit ( use in the Marantz CD94 types) & 28 pcs of the Wima MKP10 will follow with kits for diyer to exchange for their taste.
All 'E' caps was Sanyo OS-CON,Elna, Nichicon Fine, Gold , Muse,Purism Non-polar caps.
All the small watts resistors was KOA Low ppm resistors.
Large watts was NOS Western electric, Dale, CGW & telefunken
Diyers can choose CS-8412 ( USD 10 more) or 8414 version.
All fit with gold plated IC Sockets.
Use Pulse engineer PE-65612 pulse Transformer for digital input.
Cable from RCA input to PE-65612 is Gotham Prof. 10070 silver digital cable.
2. Op-amp output stage PCB.
-------------------------------------
Parts- Diode was Vishay -telefunken BYV-27-150
(Ultra-fast soft receovery diodes)
REGULATOR ICs LT1033 & 1057.
All 'E' the caps was Sanyo OS-CON,Elna, Nichicon Fine, Gold , Muse,Purism Non-polar caps.
The output caps was the best Gold Purism +125 degree caps.
Small watts resistors was KOA Low ppm resistors.
Large watts was NOS Western electric, Dale, CGW & telefunken.
One pair BB Op2604 with gold plated IC sockets.
3. Tube Buffer PCB need diyers funished by themselves.
----------------------------------------------------------------------
Diode was Vishay -telefunken BYV-56G or .
(Ultra-fast soft receovery diodes)
REGULATOR ICs LT1033 & 1057 for tube filament.
can use Battery bias or Smooth choke.
All 'E' the caps was Elna, Nichicon Fine, Gold , Muse,Purism Non-polar caps. Especially the purism Non-polar caps for tube cathode. Unless U use the Battery, otherwise will not better than use this caps.
Output Caps was USA EC MKP Caps. 600V 0.47 uf.
Large watts was NOS Western electric, Dale, CGW & TFK.
Tube Sockets was Japan style silver Plated ceremic tube sockets.
One NOS Miniwatt Dario EZ80 was follow with kit.
4. Blank Multi -adapter PCB ( Free to diyers)
-------------------------------------------------------
PCB contain 8 pcs of Blank small PCBs.
Two was 74HC74 & 74HC4040 reclock.
Two 8414 to 8412 adapter.
Four(4) single op-amp to dual op-amp. Diyers can personal buy Op-2134,627,637 for the op-amp output stage.
Directly Plug & Play is OK.
Power Transformers
--------------------------
5. Three 3 pcs of C-core power transformers with double shielding.
Pls see the photos, U will interest why the sec
winding had 0~4~5 & 0~6.3. This is special for Diyer because
they can do it by yourself for the tube buffer PCB which
change 4V (RGN1064, AZ1, AZ11 mesh plate) etc, 5V ( 5V4,
5Z3) & standard follow with kit is 6X4.
Solder wire for kit.
-----------------------
2 metre of this solder wire.
Senju Lead free & Ag-Cu-Sn solder will follow with kit for diyer. I trust that solder will effect the performace & for diyer solder Gotham silver digital cable & signal cable.
Diyers can choose Added USD 20 for one match pair Dario Miniwatt EC8010 Gold pins to relief the 6C45, but a little re-work was require..but NOS EC8010 gold pins will much better than 6C45!!!!!
Cable for kit
---------------
Digital cable.
1.5 feet Gotham 10070 Prof. digital silver cable.
1M ATM KA Japan mic cable ( very smooth sound)
1M Belden Silver plated signal cable ( more detail HF sound)
or
IM Japan Junkosha silver signal cable. This is a ultra fast digital Transmittion cable.I test they both good in Digital or the analoue output.

This is all the best that I offer to U............ Hope U will like my offer!!!!!!!!
