2x 500ma 5x20mm on digital section, inside unit

    1x 3A, 3AG (Analog Supply)  1x 1A, 3AG (Digital Supply)

Notes:

The 12AU7 output tubes are recommended to be replaced every 24 months.  The 

5R4 rectifier tube does quite a bit of power handling and as a result it may need to be 
replaced every 18 months.  The 12AX7 input tubes may outlive styrofoam.  

These figures can vary wildly with usage. It would be difficult to find an opera-

tional variable that does not affect tube life.
