calypso Posted August 18 Share Posted August 18 Item Condition: used Shipping Options: Pickup available but audition is not available.,Shipping is available at agreed cost. Suburb or Town: Armidale State: NSW Payment Method: EFT, Cash on pickup Reason for selling: No longer required Further Information: Hi, for sale is a nice matched pair of cryogenically treated 6550 tubes from Pearl Audio in Canada. I bought these a few years ago and they had a bit of light use in a SET amp I used to have. They still test better than new in friends Amplitrex tube tester. The tubes themselves are the SED winged C variety from the original St Petersburg factory. They are not the holy grail types from the 90's ( mine date from 2005 ) but still sound significantly better than latter production types when production was moved away from St Petersburg.
