Help for power supply identification
I recently bought an HRO-Senior with a power supply that does not match that
receiver type. It probably is the companion of a more recent HRO version, or of another receiver though probably still National. Can anybody help me to identify it? It can be seen at http://www.qsl.net/i0jx/power_supply.jpg The Rectifier tube is type 80. Thanks & 73 Tony I0JX, Rome Italy |

Thanks & 73 Tony I0JX, Rome Italy I believe it is a homebuilt power supply. and A very nice looking one..As I recall ,the old doghouse supply was difficult to work on, created a bit of heat and was probably not one of Nationals better designs. If it works good use it and appreciate it.I say..W4PQW |
