Coresta,

Your comments surprise me as I have graphed the tube as a triode beyond 350v with no proiblems whatsoever........

I referred to Telefunken figures before - as a tetrode the tube has G2 limitation of 200v - excess of your statement - and this figure is as a tetrode. Like many tubes this figure can be exceeded in the triode-connection.

Please explain more where your stated limitation is derived from.

If you read Telefunken figures, there is data where a single tube is utilised in AB1 modulator configuration - both with and without grid-current occuring. This tube is not a pussy - but I would hesitate to touch the glass under operation.....Each anode/plate is specced at 10.8 watts.....that's a horrible figure for the glass-size.

Telefunken-specs, which I accept, reveal that the Mugig2 is 7.5,
which is highly relevant for a triode application........

Happy to share graphed responses as a triode - pencilled on graph-paper - so they do not scan well.......better forwarded by e-mail if you seek.

Graeme,
I 've done a try at triode mode with NOS Philips ones : One plate on each tube became red before the other one :bigeyes: even at 30mA each tube ! tetrode mode is very simple for less problems of overdissipating . imho !

I have a pair of 6A6 dual triodes . I can't find any data on this.
Is this a low power triode and can this be used in a preamp ?
Anyone know how this tube sounds ?
I couldn't find any data sheets using google . Maybe I should try again.
Cheers.
