[R-390] 1L6

[Barry Hauser]

You can also use the loctal version -- 1LA6, which are still relatively
cheap.  You need to fashion an adaptor with leads as short as possible.  A
1R5 will also work, but not at the higher frequencies.  Good enough for
basic testing or using the radio primarily on the BC band.

The 50A1 ballast tube used in the later tube T-O's has also become pricey,
like the 1L6 and the 3TF7.
