General Electric 6550A -last USA made NOS tubes-
€800
This special offer is for 32 General Electric 6550A tubes. These are the very last USA made 6550 tubes from manufacturer MPD based in Owensboro, Kentucky. The former owner of Audio Research M300 amps ordered almost 25 years ago two spare sets of sixteen 6550A tubes for his cherished amps. Now this “barnfind” has become available for “tube aficionados”.
These unused tubes are now available in matched sets of 4 tubes. We have eight of these sets available. Price for each matched set of 4 tubes is 800 euro.
“When GE came out with this tube in 1971, it was a direct competitor to the Tung-Sol 6550. It was used in many high-end amps from Audio Research, Conrad Johnson, VTL, etc. When GE sold off the Owensboro, Kentucky tube works (the old Ken-Rad plant), much of
the tooling was sold to MPD. Since the mid 1980s, MPD manufactured the 6550A built to the same specs as the original GE 6550A. These were made until 1995, when they ceased production.”
