My first Doerle
This is the first one I built a few years ago. Two #30 tubes. It got me hooked. 2001 |
Replica Batteries Since most of these sets are battery powered you have to replicate old batteries too! 2005 |

The Acorn Tube Set Uses a 955 acorn triode with 2 stages of audio using a 6SN7. I went with a built-in AC power supply on this one. Its a hot little 4-band SW receiver! November 2005 |
Browning-Drake Kit This is a later model B-D kit set. Couldn't find a suitable cabinet (its a deep chassis) but I found this wood on the side of the road and went to work with it. October 2005 |
Hatry & Young Shortwave Superhet This is a replica of the HY-7 battery powered shortwave superhet built from a 1930 circuit. May 2006 |

My Ultradyne L-2 Clone This was my first attempt at building a vintage style superhet receiver. Its from a 1924 circuit and uses 8 tubes. February 2006 |
Rear View of the Ultradyne I had a lot of fun and learned a lot building this one. Its a very good performer and was ahead of its time. February 2006 |
My Reinartz Clone Coming soon....In the works is a copy of the Reinartz circuit with 2 steps of audio. 2006 |
A Haynes Receiver from 1924 This little fella is not a homebrew of my own but I saved it from being scrapped for parts. August 2006 |
Tuned Plate, Tuned Grid Shortwave Receiver This set was a bear to get working on the shortwave bands as advertised but once there it turns out to be a respectable performer.. Dec 2006 |
Grebe CR-18 (cloned circuit) This receiver was built from the plans of the Grebe CR-18 shortwave receiver. January 2007 |
4- Circuit Cockaday Tuner Detector This turned out to be a great little one tube regenerative receiver. Best one-tube design that I have encountered so far. This is the "Improved" version that came out in the publications several months after the original Cockaday circuit. Uses a 00A tube and low voltage. Presently working on the cabinet. It was made to match the 2-Step Amp. Sept 2006 |
2-Step Audio Amplifier It makes sense to have a good, versatile utility audio amplifier to try with some of these projects rather than incorporating integral audio stages on every one. Thats what I did here and this amp can be used with most any tuner design. Cabinet and layout matches the 4-Circuit Tuner and future projects can be made to match as well. Sept 2006 |
