This one looks quite good: just replace 807 with 6146W and you should be ok.

You could use a more simple design:

Thanks and regards

807 and 6146 are definitely a different beast.

Yes, 807 and 6146 are definitely a different beast, but all of them can be used to build a single-end amplifier.

To make matters more diffucult, 6146/6146A, 6146B and 6146W are three different beasts (at RF)

I have no experience with the 6146. However, from various posts and articles on the 'net, I gather that 6146 and variants thereof are not particularly successful for continuous AF duty - something to do with stability, I think. Another problem is the top cap connection to the plate, which is at high voltage and a possible above-chassis shock hazard.
