Receive:

Change C35 to a .001uf ceramic disc or mylar
Change C31, C36, C105, C107 , C102 to 2.2uF, 50 volt non-polarized electrolytic.
Change C34 to a 22uF, 16 volt electrolytic. (observe polarity)
Change C109 to a 2.2uF, 16 volt tantalum or electrolytic. (observe polarity)
Change C95 to a 1000uF, 25 volt electrolytic. (observe polarity)

Transmit:

Change C63 and C148 to a 1uF, 16 volt tantalum, observe polarity. (More bass? use a 2.2uF tantalum)
Change C147 to a 1uF 50 volt mylar. (More bass? use a 2.2uF mylar)
(Remember you can always use higher voltage cap ratings, never lower.)


To disable the AMC on AM while leaving the SSB ALC intact and adjustable:

Lift one end of R100

Hello Goldfinger:

Thank you again for your advice Sir

I will start to re-cap this old radio and in the process I will do the changes for HiFi TX & RX and install the socket for Direct Injection

Now it's time for hot iron to fill the room with flux fumes :twisted:


Best Regards
