@jomonhifi ... Whilst I fear your SF’s may prove to be a bit too much of a mouthful for your ARC REF75se on the other hand you now own a very lovely sounding 75 watt valve amplifier.
You have the option of rolling the stock factory 6h30 driver valves, V4 and V5, with a matched pair of pre 1978 Reflector Corp 6h30 DR...no shortage of info via Google.
