YAESU FT-102 SPARES
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 FT-102 SPARES

Twin meters for FT102 including lamps.
YAESU FL7000 IC METER
Found this in our FT102 spares and they do FAIL, brand new like GOLD FL7000 Linear IC Meter £25.00

We have over 100 of the original Yaesu meter lamps/bulbs for the FT102/FC102/FV102/FL7000/FT980: 20 mm long, 4 mm dia wire ended, 12 volts dc, keep it original and don't fit LEDS.

Yaesu FT102 mains switches, these do fail but we have some spares available.
FT102 RF BOARD BANDSWITCH LAST ONE
Probably the last one in the World, brand new RF Board Bandswitch £40.00 plus shipping
YAESU FT102 MAINS TRANSFORMERS:(8 IN STOCK)
We have lots of mains transformers, a few new ones and used tested ones, 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.
YAESU FT102 DISPLAY SEGMENTS:
We have new displays or the complete driver board with the display, these are VERY rare these days. Brand new never been soldered! Limited stock but we have several of the complete versions with driver ICs (10 in stock). ONLY 1 of the item below left.
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 AM/FM BOARDS:(1 IN STOCK, PRICE £75!!)
Yaesu FT102 AM/FM boards, several new and fully tested tx/rx with fitting instructions and screws, also have lots of the IC MC3359P, new unused!
YAESU FT102 RELAY KITS:
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, 1 x 12 volt double pole, a total 5 relays (RL01/RL02/03/04/05) RL02 the double pole relay rarely causes a problem and really does not need replacing, in fact a friend of mine did change his and ended up with more problems than he bargained for, but if you want one then it is in the kit as the "Teledyne 712-12 relay with a DIL socket" (RS price for this alone is £32 plus VAT).
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
Finally: Antenna changeover relay (the large one on the antenna socket) 1 x 12 volt dc (these do go as I have just changed 5)
A total of 8 relays in stock = £50.00 inc UK recorded post
YAESU FT102 PA RELAY BOARDS:(3 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:(60 + IN STOCK)
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 ( 4 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 RECT "B" BOARD & CAPACITOR KITS: (UK ONLY)
An exchange replacement board with all caps fitted (you must send us your old board first), £25.00 or a complete kit of the 8 capacitors, again we have over rated these using 105 C versions £10.00 inc UK post only.
YAESU FT102 IF BOARDS/CONTROL BOARDS/AF BOARDS/RF BOARDS:
FT102 re-worked RF boards, 4 new relays on board. Also some untested boards available for components.
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 £50.00 EACH
THE STORY OF THOSE 6146 TUBES BY PETER CHADWICK G3RZP
Click the above link to download the fascinating story of the 6146 tubes by Peter G3RZP, Peter is a Professional Engineer and Past President of the RSGB, in fact some years ago he presented me with the VHF Thorogood Trophy at the RSGB VHF Convention at Sandown Park.
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.
Received package, all OK. Installed knob and lamps...thanks so much...KC5RT................Fred
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
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
