This tube offers the classic warm 12AY7 sound with rich and balanced harmonics when pushed enough to break up. It’s a great choice for authentic tweed tones but can also help clean up amps when used in place of a 12AX7. Additionally, the JJ 12AY7 is a great replacement in 6072 microphones.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eProduct Measurements by Type\u003cbr\u003eCapacitance, Grid to Filament 1.6 pF\u003cbr\u003eCapacitance, Plate 0.33 pF\u003cbr\u003eCapacitance, grid to plate 1.7 pF\u003cbr\u003eCathode Current (Ik) ≤ 10 mA\u003cbr\u003eFilament Current (If) 300 \/ 150 mA\u003cbr\u003eFilament Voltage (Uf) 6.3 \/ 12.6 V\u003cbr\u003eGain (μ) 40\u003cbr\u003eGrid Voltage (Ug) ≥ -50 V, -4 V typical\u003cbr\u003eHeater to Cathode Voltage (Uk\/f) ≤ 90 V\u003cbr\u003eInternal Resistance (Ri) 22.8 kΩ\u003cbr\u003ePlate Current (Ia) 3.0 mA\u003cbr\u003ePlate Dissipation (Wa) ≤ 1.5 W\u003cbr\u003ePlate Voltage (Ua) ≤ 300 V, 250 V typical\u003cbr\u003eTransconductance (S) 1.75 mA\/V\u003c\/p\u003e","brand":"JJ Electronics","offers":[{"title":"Default Title","offer_id":41341242900661,"sku":"16JJE005","price":32.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/2433\/products\/t-12ay7-jj_f_0.png?v=1636597037","url":"https:\/\/www.truetonemusic.mom\/products\/jj-electronics-12ay7-vacuum-tube-t-12ay7-jj","provider":"Truetone Music","version":"1.0","type":"link"}
