• Notes

• The output of the El-Tronics was 30 watts RF according to two ads placed in the 1948 QST magazine. According to the ads, the transmitter is a five band single dial gang-tuned band-switching transmitter. The 80, 40, 20, 15 and the 10/11 meter bands are covered. The final RF amp tube is an 807. Rectifiers are 5Z4 for bias, a 5Y3 for LV B+, and a pair of 816 mercury vapor rectifiers for HV B+. The large National ACN tuning dial is marked for each of the 5 bands covered. Apparently the tuning settings were hand calibrated for accuracy.  Two voltage regulator tubes were used in series.

  The link-coupled output of the AE-30 was likely a problem for TVI. Evidence shows very few were ever sold. El-Tronics did not produce any more amateur radio transmitter models.
