Hiya mate glad you got it sorted it didn’t work when I got it that was why I changed the AF117’s and that IF core was like that when I tried to adjust it it did the same thing as it as it did on you but I got it back up but but I think the piece of elastic had rotted catch up with you later my friend
Fine Work Steve Sent Andy New Russian GT322B Transistors But Dont Know If He Got Them To Work in The Set They Worked in My RP25 And RP18 Sets Regards mike.
i've had instability problems if you just cut the screen on the AF11x things,, the small can AF12x type are 'supposedly' less likely to tin whisker but i have had one do it, so far....the OC170 and 171 are VHF capable types, used in early sw and fm capable transistor sets before the AF114, 115 and 116 were made ..i have a few ASZ20s which are 'similar' but specified for 'fast switching', they may not be linear enough for radio use

I know - I put a bit of cotton in……,

They often amplify - they did in this - but did not seem to Oscillate right ….

The problem I had was that it is relatively easy to make but not as easy to make them oscillate …..
