Well on offer today we have something quite special, I have a lomited stock of Air Ministry Old Stock audio triodes.  These fetching exquisite devices come in two forms, globe and ST shaped envelope,  with ceramic valve bases and they are really quite something.

The photos show detailed scans of the SIVCRED data sheets but for me to paraphrase, the valve parameters are as follows: -

Vf = 2V @0.4A

Vamax = 300V

For Vg = -10V for Va = 200V, Ia = 11mA; gm = 2.5mA/V 

As you can see, these ratings make these eminently suitable as am inter-stage driver valve or as preamplifier gain stage valves.  Vey rarely offered we only have a limited stock of these so please, secure a stash whilst you can.
