The 1342 was an odd amp. It was shown in every catalog illustration with an 'inverted chassis,' ostensibly to give more cooling space to the 'non-microphonic' tubes. Yet, I've found a few examples of the 1342 with squared sides.
This line ended with the unusual 1343, built by Danelectro!

Introduced:
