January 2024

It’s 2024, and we’re still at it. Our little part of far-North Indianapolis, Indiana, was annexed a while back by the City of Carmel. Taxes went up.

2023 brought some great tubes in for testing, including 300Bs, EL34s, 6550Cs, 6L6GCs, and a lot of tasty and rare Western European small signal tubes. We received tubes from all over the U.S., including Puerto Rico.

300Bs (vintage Western Electric!) came through here in late February.

We appreciate your trust.
