Mullard GZ32 NOS Rectifier Tubes

I purchased 10 new old stock Mullard GZ32 rectifier tubes to have a supply for a custom 2A3 tube power amplifier that I’ve been building. This year, I decided to quit building audio equipment for sale and am now an audio dealer for the Vinnie Rossi LIO, Harbeth speakers, and a few other very choice audio brands.

I spent a considerable amount of time and money acquiring these GZ32 rectifier tubes so I would have a future stock for my custom amps. This specific Mullard GZ32 is the absolute best sounding rectifier tube in a 2A3 tube amp. It makes such a huge positive difference compared to other alternatives that there is no other choice in my opinion. Now that I no longer need these tubes for inventory, I’m letting them go. They are in original red white and blue Mullard factory boxes (see photos at bottom of this page) and are in NOS condition at full factory spec. They have never been used!

My cost per tube was a little over $100 plus shipping cost. I’m willing to sell these incredible tubes at a slight loss. My asking price is $90 per tube plus $13.45 for USPS Priority mail shipping using the USPS medium sized flat rate box with plenty of protective cushioning. If you desire to use PayPal, add 3.5% to the total cost.

My selling price using PayPal is $120.00 (incl shipping cost)
