Needed: 2 large tuning knobs

[Doug Shields]

Hello all,
    I have an SB-401 and an HW-12A that each need a main tuning knob.  If you have any extras available please let me know the condition and your price.  Thanks very much.  Also, as I start into Heathkit test equipment I have wondered if anyone has a model O-1 scope.  I believe it was the first electronic kit the Heathkit made.  Are there any out there?   Note to Chuck Penson: Please get your book on test equipment done soon!
