Default 5687 as a single stage SE amp

Hi, guys. I want to build a simple SE amplifier with an output power of about ~ 1W. Can I use this tube in such a project? I'v heared verry good comments about it.

Regards:
Venci

It's a great tube for a linestage or driver. You can probably get 1 watt of power out of it, but the output impedance will be very high. Bass will be soft and woolly. Probably ok to drive Sennheisers.

Have you tried this design? The output power is quite enough for me

No I have not tried it. With the low parts count you should be able to test it easily.
