If you have the parts on hand, it's a shame not to use them
I always thought it was odd that some people collect huge
amounts of parts, but never do anything with them.
I am the other way around, if I have nice parts, they scream
at me to be used.
A tube or transformer is a terrible thing to waste.
I been working on the 811 modulator for the pair of 4D32's.
Its almost done, and its time to think about what to build next...
