Vintage Radio
11 Aug, 2009
Orphans have always been with us and that includes products with no identifiable manufacturer. This month, we take a look at a rather interesting 6-valve console receiver from the 1930s. It's a well-made set with no name but is one that any manufacturer would have been happy to claim.

Lead-Acid/SLA Battery Condition Checker
15 Aug, 2009
In July 2009 we presented an improved version of the Battery Zapper & Desulphator. Here we present the companion Battery Condition Checker. It gives more stable readings for all three main battery voltages (6V, 12V & 24V) than our earlier model, as well as giving a choice of test current pulse levels to suit batteries of different capacities. As a result, its now also suitable for testing sealed lead acid (SLA) batteries.
