Hi all- Doing a prelim layout of an 887 amp. Assuming adequate airflow, and assuming ½ Dia spacing of air coils, any guides for c1, c2 (both Vac Var) other than proper HV spacing? I am building a compact desktop, remote p/s. Using steppers for tuning and band switching, so little constrains the layout. Thanks for your thoughts! 73 Charlie N6CFH
