Thanks for all the information. I got a couple of replies to RFQ's and the price the vendors were asking were around $400.00 US for a new assembly. One company needed more details in order to build one and one came along with a $200 price. After putting the 4x multiplier back in the scope and powering it up without connected to the tube, it still loaded the oscillator confirming it was bad. I had to do that because originally I disconnected only the input side assuming it was the multiplier and it could have been the tube. After confirming it was multiplier for sure, I went ahead and bought the new one. I figured by the time I would order all the parts and potting material it would close to the same amount including my time. Will only repair this scope one time, then buy something new and about 1/4 the foot print. I can't believe what some of the parts houses that have bought up old inventory elsewhere are asking for parts.
Now if I can get somebody with admin rights on this site to fix my first name to William it would be nice. I apparently had fat thumbs when creating the account.
