Electro-Harmonix 6922

Electro-Harmonix 6922
$34.95

Whether boxed as Sovtek or a 6H23, these offer a warm, slightly relaxed sound, just are just a little warmer than the Type 3. 

Electro-Harmonix 6922 Gold Pin

Electro-Harmonix 6922 Gold Pin
$55.95

Slightly relaxed and a smidge warmer than a Type 3. Will round out harsher systems, and offer a palpable midrage to Sonic Frontiers or Audio Research gear.

Gold Lion E88CC / 6922

Gold Lion E88CC / 6922
$82.95

A tonally balanced tube that is durable and quiet.


Customer reviews

Customers with harsh systems find these tame the top end without losing detail, and offer lushness without too much of a tonal shift to warmth. Reviews suggest this is a greatly underrated tube.
