HW-12 tips?

[Eddy Swynar]

Hi Randy...

With a good pair of 6GE5's in the final cage, & everything properly lined
up, when you speak into the mic (normal level) with a 100-watt light bulb
dummy load (crude, but effective), the lamp should become SO bright on peaks
that it makes you believe it'll "pop" at any time...

At least that's the way it is with my HW-12A here...
