operable with the 7193 or the 6J5, RIAA phono equalization, based on the JEL FF preamp circuit
Completed on 01/19/14
Built for Stephen Dreher
Operating with the 7193s. Got to love those
"Mickey Mouse" tubes. Here are the tube specs.
Operating with the 6J5s. I first experimented
with the tube on this build about a year ago and I was very impressed with the results. Notice the toggle
switch on each channel for operation with the 7193s or the 6J5s.
I rigged up those removable grid/plate connectors for
the 7193s which can be removed when operating with the 6J5s.
