I believe it's a little more complicated: 1. If you want to use two circuits, one from each side/phase then you you should use a double breaker so that if one side blows the other one does too.
2. I would fuse each side of the circuit at the radio. (Add a secondary fuse for the plate supply primary). 3. I would provide some protective circuitry (relays) such that if you lose the low-level circuits it kills the plate supply as well. Bad for the radio and potentially dangerous if what appears to be a dark/dead radio in fact has live B+. That's my $.02 73, Mark W1EOF > -----Original Message----- > From: Rbethman [mailto:[EMAIL PROTECTED] > Sent: Saturday, April 08, 2006 12:13 PM > To: Discussion of AM Radio > Subject: Re: [AMRadio] : BC 610 needing POWER 220VAC > > > All, > > There is ONE overriding issue to think about carefully here! > > The SINGLE 110VAC feed to the BC-610, ALSO goes through a SINGLE front > panel fuse! > > IF someone desires to use TWO disparate 110VAC feeds, FUSE THE SECOND > ONE ALSO! > > Bob - N0DGN > > John Coleman ARS WA5BXO wrote: > > > I really have no idea if it is wired for 110 or 220.
