Tube Interchangability Reference

The following should be direct substitutions. To prevent damage to equipment, it would be wise to double check with a good tube manual before actually doing a substitution. Tubes in the "Tube" column are directly replaceable with tubes in the "Replacement" column. The reverse will not necessarily be a correct replacement. Please report any errors.
