Julian,

I added the special parts to the pcb list:

Dial Electronics: PIC (programmed for DE, Euro 20.00)
A-101-3: vactrols (available e.g. from Perkin Elmer or as spare parts from
us)
A-103: none
A-105: SSM2044 (e.g. Synthtec.com)
A-106-1: DS-20 (avialable only from us, Euro 20.00)
A-117: none
A-122: CEM3320 (e.g. Synthtec.com)
A-123: CEM3320 (e.g. Synthtec.com)
A-128: none
A-129-4
A-129-5
A-130: none
A-133: none
A-135: CEM3381/PA381 (e.g. Synthtec.com)
A-137: none
A-138V2
A-147: none
A-149-1: PIC (programmed for A-149-1, Euro 20.00)
A-150V1: none
A-150V2: none
A-151V1: none
A-151V2: none
A-167: none
A-172: none
A-174: joystick (ALPS)
A-176: none
A-179: none
A-191: EPROM (programmed for A-191, Euro 20.00)
A-197: meter with 10V readout

"none" means that only parts are used that are available in electronic shops
(resistors, capacitors, diodes, transistors, LEDs, integrated circuits,
trimming potentiometers, switches, pin headers and so on) except the 3.5 mm
Cliff jack sockets, A-100 potentiometers and knobs (if desired). But also
standard potentiometers can be used. The advantage of the special A-100
potentiometers is that they can be used to mount the pcb to the front panel.
I think ordering the free pcbs makes sense only for customers who have some
stock of electronic parts. If you have to collect all the parts from
different suppliers the final costs may be more than a new module !

As we have no surplus CEM or SSM ICs in stock I ask you to order these parts
e.g. from Paul Schreiber (Synthtec.com). Our stock of these parts is
adjusted to our production series of modules and we have only a few parts
left - if at all - for repair.

Best wishes
Dieter Doepfer

A-106, for example)
