[ARC5] Miniature Tube Rebuild of ARC-5 BC-453 Receiver

[Phillip Carpenter]

I picked up a BC-453 that was completely rebuilt by some Ham back in the 1960s. It works but needs tweaking and realignment. The Ham rebuilt the radio using mostly original parts but used the miniature tube versions of the octal tubes and added a built in power supply and AF amplifier with speaker.

The receiver's tube complement includes: 6C4, 6BE6, 3-6BH6s, 12AX7, and 6AQ5. Zener diodes are used in the power supply with a Triad R-10A power transformer.

The receiver is neatly built. Does anyone know of any articles of a Ham doing an ARC-5 receiver conversion to miniature tubes?

I'm in the process of tracing out the circuit but it would be helpful if anyone can shed more light on this repackaged Command Set receiver or knew the Ham who built it.
