Assembly of the second set 211 mono amplifiers of this year has been progressing well. The amps are now under test and will receive the final wooden enclosure when testing is finished.
Here a few photos of the assembly steps, starting with the top plate of an amplifier section:
The power supply sections are constructed in a similar manner.
Mounting of the power transformers:
Two of the transformers are mounted in cut outs and a bit recessed below the main plate since they would others be too high to fit under the transformer covers. Wiring of the high voltage power transformers and tube sockets:
All chokes and the remaining capacitors are mounted below the main plate. Here the finished power supply ready for testing and before the transformer covers are added. Quite a mountain of iron!

Stay tuned for photos of the finished set!
