Valves for Supro 1690T Coronado amplifiers

Supro 1690T Coronado Reissue

Best valves for Supro 1690T Coronado Reissue

The Supro 1690T Coronado Reissue amplifier uses:

  • 3 x ECC83 preamp valves (also called 12AX7).
  • 1 x Balanced ECC83 for the phase inverter (in position V4).
  • 1 x 5U4GB rectifier valve.
  • 2 x 6L6GC matched power valves / tubes.

 Note: The balanced ECC83 goes in the V4 position which is the preamp valve furthest from your input jack.

A brand new set of tubes will get your amp sounding better than ever. 

We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune. 

Remember, JJ is one of only five manufacturers in the world. So don’t pay higher prices for tubes from the same factory that have simply been rebranded by other companies.
