I have an HF-81 that my dad hand-built in 1959 that's gathering dust in my basement. I 'inherited' it when he replaced the 'old tube stuff' (*) with some Kenwood separates in 1979 and ran it for a number of years after that as my bedroom stereo when I was a teenager.
Now, the thing is, in my youthful and amateur teenage zeal, and with access to Radio Shack, I pulled and replaced all the original Eico/Mullard tubes and tossed them, replacing with "The Holy Grail RS Lifetime Tubes" which were Japanese tubes of questionable provenance. Ugh.
In order to atone for my youthful indiscretions, I want to do a full and proper resortation on the little beauty. Any tips for best sources for parts (Canadian source preferred), and any suggestions for the best replacements for the old carbon comp resistors and signal capacitors? I intend to keep all the original wafer switches.
I'm tempted to ditch the EZ-81 tubes and replace with diodes to ease the load on the power transformer. Any concerns about doing that?
Dad is almost 80 now, and it would be nice if I could finish it for him to hear again.
