A small selection of FT102 radios, tuners and VFOs, these 3 units are in daily use. We have a mega amount of spares that are left over from the Amateur Radio Yaesu Eu close down including brand new digital displays, relays + kits, bulbs, VFO bulbs, meters, knobs, front end transistors, on the secondhand front we also have many spare mains transformers (even a few new ones), stacks of knobs, cases, RF PA chokes, tuning caps, loading caps, band switches, meters, in fact we have everything for the FT102. AM/FM boards, RF boards, AF boards, IF boards, some filters, PA valve bases, rebuilt boards like the bias board, the high voltage board with new caps/diodes and resistors, carry handles, lots of extended feet for the front underside to slope the radio, grain of wheat fuses (Q 1000010 F359A BQ 0412783A original part, 10 ohms), the list goes on and on.

Yaesu FT102 mains switches, these do fail but we have some spares available.

 

YAESU FT102 MAINS TRANSFORMERS:(10 USED/TESTED IN STOCK @ 50.00 EA)

We have lots of mains transformers, can be wired for 110 or 240 vac. Sadly due to Royal Mail increasing their overseas prices these are very expensive to ship @ 5.5 Kgs packed. So collection by arrangement only.

We now have the complete driver board with the display, these are VERY rare these days, used but fully tested and good working order @ 25.00 each

MINIUMUM ORDER 20 

YAESU FT102 PA CHOKES (LIMITED STOCK):

A common problem here is the tubes going short electrodes dragging the HT down to deck after prolonged tuning sessions, high anode current shorting out the windings/turns, you should measure around 5 ohms on this unit (575-595 Micro-Henries), symptoms are low power out as the RF is going back into the PSU and may eventually take out the main smoothing caps and possibly the main transformer. 

YAESU FT102 SHAFT COUPLERS:

We have a selection of shaft couplers for the FT102 and FC102 just arrived, these are the band-switch units and the pre-select couplings, limited to 1 unit per person.

YAESU FT102 RELAY KITS:

These kits are now back in stock as of June 14th 2014

Yaesu FT102 relay kits for sale comprising of the following: (These have taken a lot of sourcing for the correct parts, ie 12 volt and 24 volt), dead easy to fit! just take your time, it takes around 90 minutes to change all relays. (I remove the RF board as it's much easier, just felt tip pen the wafer switch position or set it on 18MHz).

RF Board = 2 x 12 volt dc and 2 x 24 volt dc units, a total 4 relays (RL01/03/04/05) RL02 the double pole relay rarely causes a problem and really does not need replacing. It is not included in this package as it is obsolete.

IF Board = 1 x 12 volt dc same as RF board, total 1 relay

Local board = 1 x 12 volt dc same as RF and IF board, total 1 relay

Main relay on chassis x 1(Rarely give problems but useful to have as a spare)

Finally: Antenna changeover relay (the large one on the antenna socket) 1 x 12 volt dc (these do go as I have changed many)

These kits are now back in stock as of June 14th 2014

A total of 8 relays in stock = 40.00 inc UK recorded post..............Overseas post extra

YAESU FT102 PA RELAY BOARDS:(6 IN STOCK)

We sell lots of these to the USA and Japan, it seems that somehow the boards burn up, fitted with a new upgraded relay for the antenna changeover and antenna fuse.

YAESU FT102 ANTENNA FUSE:(LOTS IN STOCK)

MINIUMUM ORDER 20 

We have over 300 of these original Yaesu antenna fuses (FT757/102) Q1000010 F359A BQ 0412783A, approx 10 ohms in value.

YAESU FT102 RECT "A" BOARD ( 6 IN STOCK)

This board should have all 9 Electrolytic capacitors changed (new ones installed on these boards). After 30 years of use these want to be replaced and it only takes about 20 mins to do, it is worth doing as when they do go leaky then things can be costly, plus all good technicians know that it is worth replacing them with 105 C versions. Do it, don't wait for the radio to stop working or you have the common bias problems.

YAESU FT102 IF BOARDS/CONTROL BOARDS/AF BOARDS/RF BOARDS:

Just arrived from service dept: USED Control boards and AF boards plus IF boards 25.00 EACH

Tip: How to change that relay under the band-change shaft: Remove the board and remove the 2 screws holding the tufnol pillars and shaft support which is over the top of the relay, don't lose the brass spacers, next remove the circlip on the front of the shaft and slide the shaft to the rear making sure it stays in the front wafer, now you can remove the relay in seconds, fit a new one and reverse the procedure, simple and saves unsoldering the front band-switch wafers.

Just arrived from old service dept: Control boards and AF boards plus IF boards, all tested 25.00 EACH

FEEDBACK:

Feedback from Alf in Norway: .........................Hi Geoff, Packet arrived yesterday and all is well!! Relays on RF card installed and works fine. The rest have to wait for a while due to work load. I can now hear signal so very happy so far......another FT102 back to life again.

Geoff , The parts arrived today, fantastic packing job, everything is excellent. Thank you for your excellent service. When I get this rig running, I may decide to upgrade and come back to you for an AM/FM board. Hope your trip to Singapore was more enjoyment than work. Cheers Dave in Utah.

Received package, all OK. Installed knob and lamps...thanks so much...KC5RT................Fred

Hi Geoff: I was out of home during the week and returned today. Package received on Wednesday. I have just installed the new board. My FT-102 works perfect now. Thank you very much for the quick delivery. ..........Truly yours   Wolfgang Peringer DK7CY.

Problem with counter display solved. Thanks to Geoff G4ICD i could buy a complete and new counter display board for a very reasonable price. If one needs spare parts www.gwhip.co.uk/radiospares.htm is the place to look for them.............73 Wolfgang

Hi Geoff, I have fitted the replacement VFO and changed the main capacitors. I have also changed RL01 on the local board. The old FT102 is working well now and I will leave changing the other capacitors for a winter evening. Many thanks for your help. Vy 73, Chris, G4AJA
