Interesting ! I would love to see the Payson / Kunz (Read Minimal) soulition ! Maybe there is sufficent space in a '53 or '508 to control a toaster at the same time or an intelegent remote control for all ocassions . If it wont fit they will probably make it............. Cheers Steve..... I might consider this myself as current UV box is RUBBISH (no timer cutout or human protection) Its left behind filing cabenet to shine at cieling and chips are placed on top of tube by hand .............
