    122 crossover capacitor replacement

    My values were 3 times higher than original. I swapped the 7.8mf/12.5mf with a 10mf/15mf. It sounds delightful now!
    I may try 8mf/12mf just to hear if it makes much difference. I went with 10/15 -100v to simulate aging. Anyway...it sounds fine to me.
    BCV, C2, M3, C3
    HR40, 142, 760, 771
    Once upon a time I was a musician, now I just collect Hammonds!

    I kept it simple and took the suggestions of those before me:

    I looked at that one from Trek II. $40 and simple... So I opted to go with another combo in caps. 6.8uf and 1.uf for 7.8 in parallel and 10uf, 1.5uf & 1.uf in parallel... I will let you know how it works out...
    I rebuild Hammonds and Leslies. Please visit my website. tbstonewheels.com It's still in the works but is up and running. My personal setup is a Model A # 2203 with Trek II percussion, 122RV and 2 31h's. One is fitted with two speed motors and the other a Hamptone. Also sporting a working Vibratone 30A # 326.

    I just replaced the capacitors in my 22H/122 with the Trek unit and what a difference! I think it took all of 30 minutes from beginning to end to install. I had purchased the individual caps kit from TWGH a while back, but lost them in a move, so this was the quickest solution. Also, spent another few minutes doing the Percussion 'Normal' volume drop modification to the B3.
    Current: Hammond B3/ B2 cabinet, Leslie 122/ 22H, Hammond M3
    Past: Hammond CV, Hammond D20, Leslie 122a, '63 Hammond B3, '62 Leslie 122
