New Matched Pair (2) Telefunken 6550 Vacuum Tubes

New Plate Current Matched Pair (2 pc set) of Telefunken 6550 Vacuum Tubes

An excellent power tube Telefunken fit for classic amps such as Ampeg, capable of delivering a full 35-watt output. This is the ideal tube for warm tones with smooth overdrive in guitar amplifiers. They also happen to sound incredible in hifi applications with rich dynamics. 

Testing and/or Matching

Tested and/or matched at full operating voltage on a Maxi-Matcher tube tester for both Ip (Plate Current) and Gm (General Mutual Transconductance). We always TRY to match by 5% when we can (90% of them time) but our cut-off matching parameter is +/- 15%.
