To order parts, simply send your payment via Paypal to firstname.lastname@example.org with what you require, if you are in the UK you can send me a cheque made out to Derek Revell, 20 Sage Close, Biggleswade, Beds, SG18 8WH.
Please note there is a minimum order for small items to cover postage and packaging, but if you only want single items, then email me and I'll prepare an individual quotation for you.
I may have to improve the payment methods, so you can place your order directly from this page via Paypal.
A small selection of what I have on sale. Orders for more than £25 qualify for free delivery within the U.K, orders for more than £50.00 are free for the rest of the world.
The K1C 6mm screw fitting and satin knobs are Cliff knobs, and have a matt silver finish, the insert which can be easily be removed, after soaking the knob in very hot water for a minute or 2. I can supply the K1 knobs without the silver insert, where you can make your own inserts.
The semiconductors are 100% tested prior to dispatch, BC258B replaced 2N4288 and 2N5172 replaced BC169C, these are now used in later models of the original Deodar synthesiser's, I haven't heard of any difference to the operation of the circuits if the original 2N transistor types are used.
I've got a few hundred Cliff Knobs, and I've found a good source for the coloured inserts, ask me if you want a set, I charge £60/set 33 off knobs including 3 off Blue Inserts for the Vernier Dials, or buy direct from Cliff here. and CLICK on the ROTARY icon.
Vernier Knobs, can be sourced from the USA, usually available on Ebay.
TAB101 can be obtained in the UK here or from the States here. but my last enquiry to the States, was answered promptly, that they had NO STOCK. I have found that later Deodar synthesisers now use a Motorola device which is MC1596G but the circuit on the board has been altered to use this device.It has been suggested that CA3046's or a MC1596H can be used, but as these are both 14 pin DIL IC's this would need the chip to be mounted on a Veroboard or similar, and the device has 5 transistors not 4 as in the TAB101, or it could be possible to simply bond together 4 off BC169C together and change the wiring to suit the PCB holes.
MFC6070 here. (sadly no longer avallable) I'm looking for a suitable replacement maybe with a modern 8 pin DIP. It's possible to adapt the same circuit that is used to power the internal speakers, to drive the reverb tank. I notice that Deodar synthesisers no longer use this device, but have changed the circuit to use a 741 and AC173K and AC153K transistors. I am investigating using the same improvement. I see that doing a "Google" search for 'MFC6070 for sale' brings up a Amazon source in America here, most bizarre, beware of UK Government levied Import duties.
ME9002 (6) are extremely difficult to source and expensive to boot, but BSX20, NTE107 or 2N2369A are good substitutes, but ME9002 should be available here.
32 Way edge connectors, I have found a good supply on Ebay, the supplier is in Taiwan, and are 100% reliable, the items are without mounting feet, and have 64 contacts i.e. double sided, but they are OK for soldering. I have obtained 50 off, and I suggest that mounting feet be made from aluminium 'L' shaped angle and be epoxied to the ends of the connectors, you can buy your own connectors from here. It's a good idea to solder these connectors to a veroboard strip and do the wiring from the board, much easier than soldering wires directly to the pin legs, and also more secure as you can reinforce the veroboard with a top coat of aluminium, if you so wish.
2N5172 (57) O.K. to use BC169C.
2N4288 (30) O.K. to use BC258B or BC214L
2N5163 (6) use the equivalent BF245C, the Vp on these devices is 3.4V.
2N5461 (1) these are readily available.
AC153K and AC176K are available at Cricklewood Electronics in the UK, with a slightly high price tag, but as only 2 of each are required, that 's not too expensive.
BFY51 (2) available on Ebay usually.
DK10 (6) is a small signal germanium diode, use any small signal diode like OA47, 1N34A or 1N60 etc, etc, look on Ebay for Germanium Diode example.
TIP3055 (2) usually available on Ebay.
16 x 16 Sealectro Patch matrix obsolete, try Ghielmetti here. If you require a 16 x 16 Custom 621 Matrix you may find that you have quite a hefty bill, €528 + €60 carriage + €20 import duty + 20% VAT, although a standard Type 621 20 x 20 maybe around €287 + €60 + €20 + 20% VAT, in my opinion if you're serious about making a decent clone of either a VCS3 or Synthi A, the decision not to buy a matrix would be completely missing the whole point of cloning, I would advise that a cheaper option would be to buy Doepfer units, and put them in a briefcase.
Accutronics Reverb Tank available Part # 1BC2D1B here.
Images for making the 6 way edge connector for Q1 and Q6 here.
Special Black profile edging strip to finish off the Synthi Zee now available, which is a better profile than EMS supply now.
I've been asked many times for a link to a XY Joystick please try this LINK
PCB's available ex-stock as from March 2013.
I do supply 25 ohm speakers, but I must admit these are not the best sonically, I see that Rapid have a wide ranging speaker available here, although they are 4 times the price, and are actually only available in an 8 ohm version, but are sonically superior to my 25 ohm speakers I am selling.
