Thomas Mayer SE 211 Amplifier Production

Thomas Mayer in action. Three pairs of 211 drive 211 single ended amps being built with a similar arrangement as recently shown differential 300B amps.

You can see on the photos pre assembled sub modules which go inside the wooden chassis, top plates for one set of amplifiers.

The shorter stack in front are the modules with the final filter chokes that will be mounted in the amplifier chassis. On the right sides there are two rows of modules with the large vacuum varnished B+ transformer and the separate DC filament supplies for driver and output tubes.

Few highlights:

Tribute output and interstage transformers
NOS paper in oil caps for the critical sections.
Elrog ER211 tubes
Alternatively these amps can also use the new ER242C tubes
