Yes, the Type 26 and 76 are very nice tubes, have used them and they are among my favorites. The JJ 2A3 is a fanatastic tube for the money, I am doing a SE stereo amp with a pair of JJ 2A3s - right now.

Your toplogy schematic can be greatly improved, ( and you will hear it on K-Horns ), by simplifying, as I suggested above with the 211 proposal.

Eliminate three unwanted components, the two 0.22 uF series cap couples, and the middle tube stage. You will gain transparency. Study " Loftin White " as a start ( and maybe a finish ). Its common sense, a triple run of 19 AWG pure silver wire about three inches long, will be higher fidelity then the three series parts I suggested you eliminate.

I can send you data and complete write ups on this, next week, when my computer gets home from the repair shop. Just email me, address above.
