Description

New Matched Pair of Sovtek 6H30Pi Vacuum Tubes

Matched by Gm & Gain & tested for noise. A super-powered tube most closely related to the 6922. While it is not a direct replacement for a 6922, it features much higher transconductance but having less gain as its counterpart for lower noise. Sovtek brings incredible reliability with their tubes.

Will work in place of: 6H30Pi, 6H30P, 6H30P-I, 6H30Pie

Testing and/or Matching

At VIVA TUBES, all of our customers get the same high standard of testing and matching. Some sellers charge more for premium matches but we believe all of our customers should get the same level of quality and service. 

Tubes are tested and/or matched at full operating voltage with regulated power supply on a Maxi Matcher tester for general mutual transconductance (Gm). In addition, power tubes are tested/matched by plate current (Ip) and preamp tubes are tested/matched by gain. Rectifier tubes will be tested for emissions on a calibrated military grade tube tester. 

Our goal is to match within 5% with an upper limit of 15% (15% is the industry limit to consider a set).

Hand written test data included.

Note that we do offer a few models which are tested & matched at the factory. They will be matched by the same parameters (Ip & Gm) but to the manufacturer's standards. Factory testing will be indicated in the item title and description. 

Guarantee

We offer a minimum 90 day guarantee covering functional defects - including noise unless otherwise stated. The guarantee period begins the day you receive your order.

    Sound quality between Mfg. date codes

    Posted by Michael Bueckers on 26th Nov 2020

    2012 sound the best (5). 2010 not sound or mechanically good. 2015 in general sound ok. 2017 way less second order harmonics. Sound is not sweet and tube like. I have 98 of the pre 1990 millitary grade green box. You have to purchase 2 to learn about these.

    These triodes sound great.

    Posted by Michael Bueckers on 2nd Sep 2020

    These triodes are date code of 2017 have a different sound than the ones with date codes back between 2002 and 2015. These newer triodes have a more detailed and clear sound. Not as 2nd harmonic rich as the older ones.

    Must burn these tubes in for at least 25 hours.

    These tubes will not have the sweet 2nd harmonic sound until they get broken in. These tubes soung good.
