Electro-Harmonix Platinum Matched 7591A (each)
Art Audio has opted to sell only factory matched Platinum Electro-Harmonix Tubes.
Smooth, yet punchy, with a sweet harmonix finish, this year's vintage from New Sensor. Ampeg owners, rejoice! Replaces the Sovtek and does not require the resistor mod.
Typically ships within 3-5 business days.
