Hi all
I put a 89t in my 1946 magnavox with W-C 256 changer, (it is a Magnavox Duette it has the CR-187 chassis with p-p 6L6 with two 12 inch speakers) it is easy to do and it works fine I experimented with some changes in the phono input and made it sound a lot better the 89t likes a high resistrance load. The orignal had a .0001 cap between the pickup and the grid of the amp. I put a 1 meg across this .0001 and put a 22K in series with a .0015 from the pickup side of the 1 meg resister and ground. It added some bass and to me made a better middle range. I did not remove any of the orignal so I can go back if I want, but really sounds good. I agree the radio on Ebay is a bit to much for my pocketbook.
Just a thought.
