Dual Rectifier Adapter

What happens when there is no more stock of 6H6 dual rectifier tubes, but plenty of 6AL5 tubes?  This situation clearly calls for an adapter.

Take a base from a dead tube and remove the tube by breaking it and de-soldering the leads.
Take a tube socket from an old TV chassis and wire the leads to match.

The result is a convenient adapter that can be applied to a classic radio without making any modifications to the vintage equipment.
