Re: Actually if you research......

Tubes for the Dynaco are pretty reasonable except for the 7199's.

Svetlana EL-34's-around $15.00 or less apiece.Sound very close to the old Mullards IMO.

NOS RCA or other USA NOS branded 5R4 Rectifier-around $10-$15 in place of the very expensive Mullard 5AR.Many including myself like the sound of a 5R4 instead of a 5AR4.

NOS 7199's...yes quite expensive IMO at around $30.00 a piece.
The word on the street is to stay away from the cheaper new production 7199's.

As far as caps go....yeah a multi-section cap replacement is a little
expensive.The Black Cats are also something to watch out for leakage.
Although mine seem to work just fine(I had a good tech fully check over my Dynaco ST-70 as well as get rid of the selenium rectifier in the bias supply)."If it ain't broken don't fix it!"

Even with this cost the Dynaco ST-70 is still cheaper and sounds FAR better than most "Hi-End " money-pit amps of today IMO!Although the SALESHACKS will lead one to think different.
