For sale an UU6 full wave HT rectifier valve / vacuum tube by Mazda, recently fully tested and working at 100% of nominal new emission on both sections. It is on an MO base (see below) has a 4 volt heater and can supply a maximum of 120mA at 395 volts. As with the vast majority of Mazda metallised rectifiers, the top half of metallising along with original markings has mostly flaked off (as usual!) This doesn't look so great, but the metallising is not required and when it flakes away, it actually helps the valve work a but cooler!  

This valve is on a Mazda Octal base which is NOT the same as the more usual IO (International Octal) base. Only buy this valve if you have an old radio that uses this style of base, or you have an MO base in stock to use with it.

The UU6 is a general purpose rectifier for use in standard domestic equipment, mainly table top radios. This is an ideal spare or replacement if you have a treasured old radio that uses a UU6 in its power supply.

Fully tested on my Mullard High Speed Valve Tester and showing zero faults and 100% of nominal new emission on both sections. A reasonable price for this now rare, fully working but mid-life examples of a still sought after valve/tube.

If you have a treasured vintage radio that uses a UU6, here is your chance to acquire that very hard to get spare in guaranteed working condition or your money back.
