the ultimate guide to tube-rolling: 6922

A high-transconductance small-signal tube

6922 / 6DJ8 / ECC88 / E88CC / 6N23P / 6N11

A miniature nine-pin medium-gain dual triode with very high transconductance. First developed by Amperex / Philips for use as an amplifier in TV tuners, and later used in high-quality oscilloscopes.

Great extension and nice mids, but too microphonic for anything but the driver or buffer grade.

Electro-Harmonix 6922

$29.95

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
$34.95

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.


Customer reviews

The reviews bear out Kevin's description above, and the tubes seem to last a long time too. 

Matsushita / National PCC88 / 7DJ8 (NOS)

Matsushita / National PCC88 / 7DJ8
$58.00

A sense of ease and grace that all the best NOS tubes have. Similar midrange to a Telefunken 6DJ8, but with better top and bottom extension. A lovely organic sound.


Customer reviews

Customers report expanding soundstages and better instrument separation. "Organic", "natural sounding", warm but with top-end presence. Many customers love the detail they hear, but without ever losing that natural quality. "Natural" is probably the descriptor that comes up most frequently. The caution would be if you had a laidback system, they might limit dynamics too much.

A clean top end that maintains extension without being bright. Neutral mids and a wonderful, tight bass.


Customer reviews

Customers report a big improvement in bass, and echo that there's top-end presence without it being too bright.

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.

6H23 / 6922 Type 3 (NOS)

6H23 / 6922 Type 3
$84.95

The most durable 6922, very clear in the mids, great extension top and bottom. Less warm than a Type 2.  Detailed and dynamic.


Customer reviews

Customers back up the durability of this tube, saying they were quiet and stayed quiet for far longer than any other 6922 they've tried.

and classically trained musician loved their harmonic accuracy. Good "inner detail" comes up often, and does tighter, deeper bass.
