If you do run into a pair of 6A3s that test poorly, and can't find a new pair for a realistic non audiophool price, then you could use a pair of adapters to use triode connected 6L6s as substitutes. The only issue may be with regard to biasing the tubes, but they will handle the voltages quite easily. Fortunately I don't think that 6A3s are to the level of stupid where the type 50s are as yet.
