"Same Old, Same Old" says Ye? "Bologna" says I....assuming they had bologna back when they talked this way!
This puppy is Bullet Proof all the way around....except from the bottom I guess. Yes, this 1/2 inch plastic material is indeed the famous 'Bullet Proof Glass' and is sold by the pound....just like GOLD! When paying for it one quickly sees that it would be cheaper to buy GOLD!
Anyway, this receiver tunes the AM band with a twin #30 tube regenerative schematic from Mike Starcher's site. Thanks Mike! I adapted 01A's for my set though since costs were already out of sight on this project. The interstage transformer is a completely refurbished ERLA which, regrettably, is not displayed will in any of these pics. The antique variable capacitor was also refurbished but is only slightly more visible than the transformer.
The tickler coil in the variometer is Honeycomb construction and is rotated with the knob on top with a very fifty timing belt and pulleys set up. Very slick! Both primary and main coils are cylinder type with the main coil being space-wound on a clear acrylic form. The entire coil assembly is suspended above the wood base by the styrene shaft that operates the tickler. Better 'Q' you know!
All wiring is done with cotton covered copper wire. B voltage, A voltage, Antenna and ground connections are all made with brass binding post located behind the tubes. B voltage is 45VDC and A voltage is 5VDC & .25 amps.
Both knobs are hand made using Ebony for the grips and padauk for the skirts with padauk center buttons on each. They and the base are stained and then 'shaded' with my own lacquer mixtures. Final finish is done with my own flattened nitro celluloses lacquer.
