I bought this of eBay for £16+P&P, the frequency dial and the potentiometer are missing,
but all the boards are there, so i think it's going to make a for a nice little project.
(IMG:FG1_1.jpg)(IMG:FG1_2.jpg)(IMG:FG1_3.jpg)(IMG:FG1_4.jpg)(IMG:FG1_5.jpg)(IMG:FG1_6.jpg)
it's all working now,
(IMG:FG1_7.jpg)(IMG:FG1_8.jpg)(IMG:FG1_9.jpg)(IMG:FG1_10.jpg)(IMG:FG1_11.jpg)(IMG:FG1_12.jpg)(IMG:FG1_13.jpg)
i was able to find a 5k pot for the one that was missing for the frequency adjustment (it's a bit of a hack but it will be fine for now),
(IMG:FG1_14.jpg)(IMG:FG1_15.jpg)
i was also able to find some replacements for the missing capacitors too (a 10uf for the 10sec sweep and a 10uf for the x1 frequency range),
(IMG:FG1_16.jpg)
i also replaced the 47ohm resistor and the two clamping diodes on the main amp board (the 47ohm resistor tested fine but looked burnt),
i also fixed the neon indicator on the front, cleaned the card connecter pins, switch contacts and fitted a power lead.
(IMG:FG1_17.jpg)
i've replaced the 5k potentiometer with a 10 turn 5k pot, i got off eBay,
to give some finer control, it's not the best, but it works better then the single turn pot i put in.
