Just want to let people know that have tried the 6H6P NOS tubes in place of the 6H30 Sovteks in my DROPLET CD player and the sound is excellent!
Very impressed with the mids , highs and bass is all very very good indeed. I think they are way better than the Sovteks thats for sure. These are very long life tubes as well and cost a fraction of the price of the 6H30DRs and much more easily attainable as well!
Give them a try!
