It needed to be done tho because of the lack of voltage amplification in the output stage, or very little by comparison to a conventional output stage. One time I put in a pair of 6L6gcs in one of my Mc60z..It sounded very good but what happened was it sucked in the side of the glass and warped the inside of the tubes.
Now under most conditions a 6L6gc biases up like a 6550 as far as negative bias voltage and plate voltage goes..I had put 6L6gcs in the citation 2 and no such thing happened but I did reduce the current to about 50ma a tube.After seeing what I saw what the Mc60s did,I had no trouble believing doc when he said current amplifies thru the output stage of the unity coupled circuit..
