martin.m, it is always good to see a working Hacker !

Looking at the pictures I see quite a few 'lockfit' packaged transistors, both on the audio panel and the IF panel. Although these are silicon devices, experience has shown that because of this particular packaging they can and do develop faults like low gain and/or noise. So should your set develop such faults - which I hope it does not - bear this point in mind.
