EC8020 Differential Phono Stage - Part 2


In the first post about the differential EC8020 phono stage I showed the initial steps of the assembly. In the meantime the signal unit is finished.

All the socket sub plates mounted and heater connections wired:

Some transformers and inductors are placed on the top side:

These will later be hidden under transformer covers

All signal connections done with solid core silver wire:

All remaining components get mounted on a separate metal plate:

This is attached to the top plate:

The completed signal unit contains a total of 28 transformers and inductors!

Another 6 transformers and chokes will be housed in the separate power supply.

As soon as the wooden frame is finished the unit will be put into the housing. Stay tuned for the next part which will show the power supply assembly.

Best regards

The second day of this years Bath AudioFest is on.

The system got tweaked a bit...

This gives a bit better distribution of the sound into the room. A quick sound check:

300B Mono Blocks in Tower Style


The 300B monos in the tower style chassis are finished. These will go together with the 10Y line stage shown earlier this month. And will be used with power supplies in the same style.

These amps use the same circuit design and parts as the 300B monos built last summer. Just the chassis style is different. Signal section of one channel:

The interstage and output transformers are made by Tribute

The interstage transformer is placed on the top while the larger output transformer resides inside the chassis.

The tube sockets are on sub plates mounted below the top plate.

The two mono blocks with the matching line stage:

With tubes lit up:
