Driving an 801 or 10Y with another DHT would be tricky. The driver stage would need a Zout of <400 ohms. A 2A3 might do it via a step down interstage although making a good interstage that'll handle 60mA will be difficult. A 45 at near maximum ratings via a 2:1 step down might also just do it (but not with much to spare) The smaller DHT's just wouldn't swing enough volts once the necessary step down was applied. Shishido used the 6EM7 and a step down but that isn't a DHT.
