Subject: [ARC5] Equivalent tube types


> Dear list:
> There are well known equivalents (long life, high reliablity) to the
> 12A?7 series of tubes.
> (See?  you guys have corrupted me.  I now call a "valve" a "tube"!  
> Aaarghhhh!  My soul is bound for perdition ....)
> 
> Can any-one tell me the numbers?
> It's 6000 or 9000 or some number like that.
> 
> Ditto for the 9000 .. 9003 types.
> There are "common" equivalents for these.
> Can anyone help?
> I have an ARC VHF set that uses these tubes but there are some that are
> hard to get.
