On Mk3 "Z" board
1) R173 should be 1K8 not 18K
2) R174 should be 18K not 1K8
This effects the Control Voltage Centre Zeroing on the moving Coil Meter M1, in the past I wrongly assumed that PR14 should have been 100K, which fixed the fault, but the schematic is correct PR14 is 10K.
2 TRACK ERRORS
On MK3 "Y" board
1) The track from Q24 goes to Base on Q21, the track should go to middle leg of Q21.
2) C47 wrongly connected to 0V, remove track link to double connection on C47, use 2.5mm capacitor only. Pictures of corrections here.
If you do not want to use the edge connectors, and would prefer to make the connections to the boards via a DIN 41612 Euro plug and socket, and Molex 7 way connectors only. I can now offer alternative boards at a reduced price of £60/set UK and £70/set International posting.
Need a complete VCS3 clone kit
, "The Cloney Project " by Matthias Armstroff, maybe your answer, please visit his Facebook page here
Just fitted a S&H mod to my EMS Synthi A, from Constantin in Belgium, awesome mod, very good value, works beautifully, and doesn't require drilling or extra switches, link here
KS info moved here.
An excellent place to find some Phutney electronic components Silicon Ark here
Looks like Robin Wood has let his web site expire, I found another link to it, Peter Zinovieff has taken over the original web site,it still hasn't been updated since 1998, link here
More errors found on the BOM, added some Pin Out data on the wiring diagrams, corrected some missing links and incorrect data in the write ups, mostly on the Phutney Tech Page.
I've added wiring information on the TIP3055's to the 6 way connector to Q1 and Q6, this can be found here
I've modified some of the Phutney schematics, these pages marked NEW on the Tech Page, on these I've added the Input, Output and Level Pots, I would like to know if these are preferable to the schematics. without the I/O and pots.
I've updated the TTSH project page, after receiving the rare parts from Thonk.
There is a minor error on the Mk1 and Mk 2 "X" board, this is a missing 10K resistor, omitted from my original Synthi AKS, that's how it got missed on the clone.
Added pot wiring information for Mk3 boards.
Added more names to Cam Gears page.
Added DIN 41612 plug and socket availablility.
Mk3 BOM added to the Technical Page.
Updated Photos of Mk3 boards on Clone Part page.
Added Z component layout in PDF format.
Added Backplane to Clone Parts page.
Added backplane connector info on Cloned Parts page.
Managed to obtain some more scarce components for the "Phutney", be aware that there is free delivery in the U.K. and £9.75 Intl.
