Aesthetix Rhea 6922 Tubes

I have to change my Gold Lion 6922 tube in V5 in the Rhea as they have developed Microphonics after one year. Which tube will be good there.
1- Electro Harmonix 6922.
2- Matsushita /National PCC88/7DJ8. Don't know if they can be used in Rhea but Upscale Audio has them listed.
3- Go back to Gold Lion.
Thanks

Two suggestions:

1. Call Aesthetix and ask Glen.

2. Andy at Vintage Tube Services is familiar with and recommended by Aesthetix. I used his services when buying NOS tubes for my Aesthetix equipment. The results were excellent.

If the Rhea can use the 7dj8's I highly recommend the Matsushita/National Unions from Upscale. They sound excellent transparent with good extension and fairly neutral. And they test super strong and really last.
