Custom Hammond Power Transformer
#1

Has anyone ever gone the route of requesting a custom transformer design from Hammond? The transformer on my 46-480 looks to be in horrible condition. It’s heavily rusted, which has me worried about eddy currents in the laminated core. The holes for rivets are also all broken off, except for one. I’ve used their online request form to reach out with details of what I am needing.

Per the available Philco parts catalogs the Philco 32-8243 transformer is a 117V, 60Hz primary to 640V @ 85mA secondary. It’s got a 6.4V @ 3.45A rectifier output and a 6.4V @ 0.3A center tapped filament output. This is obviously very uncommon, and I can’t find a readily available replacement.

If anyone has gone this route, I’m curious about the turnaround time and pricing. I’m also entertaining a rewind, but I understand that this isn’t really any cheaper.
