Hi Abe,
Sorry ,I ment to get back sooner,forgot...Age
The Cunningham 45s did not test well at all,however I do have apair of RCA 45 Radiotron black plates later vintage that are used though test fine. Is $20.00 each too much?
Crazy thing I have a dozen or so 1920s vintage 201A and 301a Cunninghams that came with the bunch that all but one test great.
I ment to ask you ,how does your Haggerman phonostage compare to your Chenin?
