Default In 1964 Crown introduced his first solid state amplifier, the SA 20-20

.... I read there:
Crown Timeline
Crown International - Wikipedia, the free encyclopedia
Also about this amp I cannot find more except one small photo
... in opposite to the 1967 first released DC300(A) - here I find all wanted informations about
Discontinued Amplifier Products
and there
Crown Amplifier Technical Information

Crown's SA20-20 was tested in the High Fidelity magazine from April 1966. This I have found by the complete overview about

Default Vox Solid State "Super Beatle" Series from mid 1965:

By mid 1965, Thomas Organ had discontinued selling the AC-100 in favor of their new solid state models. Four models were introduced before the ending of production in 1970; the V1141, V1142, V1143 and finally the Beatle Super Stack. The V1141 and the V1142 were similar in every detail except that the V1142 did not feature the distortion effect. The V1143 was similar to the V1141 with the addition of a "G" tuner and Repeat Percussion effects. In addition, the V1143 model was manufactured with Field Effect Transistors (FET) transistors. This was true for all VOX models ending with the number three (3). The Beatle Super Stack was a V1143 with two 4x12 speaker cabinets similar in appearance to a Marshall stack.

Schematics not to find and wanted. Here the URLs and some pics:

Default The first Single ended Solid State diy Power Amp from 1956

The schematic of the 1956 amp is shown above. There are four germanium transistors, a technology still new to experimenters at that time. Of special note is the 2N68, which had just been introduced by Sylvania as a “PNP medium gain, high power transistor for moderate frequency applications”. What this meant was a maximum of 4 watts output (using the massive metal heatsink for heat dissipation) at a frequency of 400 kc (yes that’s kilocycles). This was “state-of-the-art” for 1956 germanium power transistor technology. The three front-end transistors were all from the well known Raytheon CK722 series, and best results could be obtained by “hand selecting” individual transistors.
