[HAM] ADDED INFO: Help Please? leslie 45 with 147 amp -

[joe d]

added info:
I will not connect this 147 amp to my Ham with 122 type kits (risk of 
blowing things).

I would want to rebuild this 147 type amp into a 122 type amp, rather than 
install a kit to accept 147 leslies in the organ.
What is involve with turning a 147 amp into a 122 type?

thank you for any advice
