Cathode Follower (Read 10146 times)

Tubeman Senior Member Posts: 77	Cathode Follower 08/23/17 at 19:30:15 I am selling a professionally built 5687 cathode follower that is very similar to a Z-Box. All premium parts and wiring. Tube is included. Asking $200 to recover the parts cost. Additional photos available.

Looks to be a great product. Like the looks of the Edcor transformer, and the use of a 5687 tube. For my own information, what size fuse does this circuit use, and do you know the input and output impedance? Again for my sake of curiosity, what size film caps are used in the output?
For those that may not know, I purchased a headphone amp circuit from Tubeman awhile back. I barely have words beyond *wow* to describe the sound. And the build quality approaches museum display.

Tubeman Senior Member Posts: 77	Re: Cathode Follower Reply #7 - 10/25/17 at 14:20:28 Yes, I did build the cathode follower. And yes that could be added to the circuit. I would suggest building it in a separate enclosure so it could be added or removed as needed.

The headphone amp that he worked on with me turned out to be one of the best pieces of equipment that I have ever owned. This should have been a no brainer from the start, but I woke up and now, well, it's mine.
