Live from Munich : High End 2019, Part 6

Hi!

Another premiere at this years High End is the first public demo with the newly developed Elrog ER888 tube.

The ER888 is a new tube type which never existed before.

It is the molybdenum plate cousin of the ER887.

Made to drive the ER284 output tube.

Visit us in room F231e to listen to this new tube.

Best regards

SE 845 Mono Amplifiers

Hi!

Here some photos of newly finished single ended 845 mono amps.

Like a previous set of such amps these use a specially designed Elrog tube as driver. For this purpose we developed the ER887, of which there is now also a molybdenum plate version, the ER888.

The driver tube is on the left and instead of an 845 this amplifier gets a set of Elrog ER284, also with molybdenum plate.

The power supply uses a pair of Elrog ER274A rectifiers in conjunction with two 6AU4 TV dampers for slow ramp up of the high voltage.

 Power supply and amplifier of one channel:

Two separate heavy duty umbilicals connect between amp and PSU. One for the filaments and one for the high voltages:

The stereo set consists of 4 chassis:

The amplifier in operation:

The filaments are visible through the slotted plates.

Since these are customer amplifiers they will not been shown in Munich, but I have another set finished in different color scheme which will be on demo at the high End show next week:

Come to the High End and visit room F231e to listen to these amplifiers.


Best regards


Thomas
