Note: Earlier this year (2007) Sovtek abruptly ceased production of the 7199 (Triode/Pentode) tube. The remaining supply of these tubes have already become increasingly scarce and costs have risen sharply. NOS types of this tube will soon become unobtainable. Accordingly, Dynakit has selected the 6GH8A (Triode/Pentode) tube as a direct replacement for the 7199 tube. The 6GH8A has very similar characteristics to the 7199 tube with the added benefit of it’s abundant supply and reasonable cost.
The 6GH8A tube is not a "Drop-In" replacement for the 7199 tube and pin-out changes are required, however, to simplify this Dyankit offers a special plug-in 9 pin socket adapter which addresses these changes while retaining the original Dyna circuitry.
Our special socket adapter #SA-6GH8A will be provided with both our MKIV and ST-70 amplifier kits at no additional cost. It can also be purchased separately for use with any amplifier currently using the 7199 tube.
The 6GH8A tube is available through our affiliate ANTIQUE ELECTRONIC SUPPLY in addition to the 7199 tube while supplies last.
