807 Testing.

[Diabolical Artificer]

Yes Tracey, you would have thought so. My friend who sent it me from the USA was of the opinion that the postal service was to blame, but the valve has little mass as does the htr bonding wire, which would have been contact welded to the htr itself, it would take a prodigous knock to dislodge it.

Going to put the crazy 807 in an amp, to try and see if oscillation is occuring.
