RFT ECC83 – Made in Germany. These are an often overlooked NOS 12AX7 that was made in Germany. They are low noise, low microphony, and are great in circuits that may be a little tough on other 12AX7s. Somewhat relaxed on top, but they are typically known for having a edgier sound in the mids and bass, not a liquid midrange like a Mullard. These came to us in bulk packing so we pack them for you in generic boxes. Price includes matching at no extra charge.
Platinum grade - The best of the best. Lowest noise and microphony with the tightest triode balance we have available. This is typically 10% or tighter, but may be higher depending on available stock.
