Very low plate resistance and high current capability. Indirectly heated cathode, octal base. The 6N13P (6Н13П) is the civilian/industrial grade; the 6N13S (6Н13С) is the military grade with tighter tolerances. Pin-compatible with 6AS7G and 6080.","is_directly_heated":false,"completeness":"high","notes":["Cyrillic designation: 6Н13П. The 'П' suffix denotes civilian/industrial grade. The military grade is 6Н13С (6N13S), which has tighter parameter tolerances and extended temperature range (-60 to +70 C) but identical electrical ratings.","The Soviet datasheet specifies ra as '<=460 Ω' (an upper limit, not a typical value). The Western equivalent 6AS7G specifies ra=280 Ω typical. Actual ra varies with operating point.","The Chinese-made 6N13P (e.g. Shuguang) may have different characteristics from Soviet-made tubes. Some Chinese sources list mu=24 and ra=400 Ω, which appear to be erroneous — inconsistent with the tube's known role as a 6AS7G equivalent.","Guaranteed service life: 1000 hours (civilian 6N13P) vs 2000 hours (military 6N13S).","When used in compensator-type electronic stabilizers, the grid circuit resistance may be up to 3 MΩ (vs the standard 1 MΩ limit).","Va_max is 250V in continuous operation, but 500V is permitted momentarily when switching in with a cold tube."],"references":["https://frank.pocnet.net/sheets/113/6/6N13S.pdf","https://soviet-tubes.com/product/high-quality-double-triode-6n13s-tube-low-resistance-strong-signal-amplification-great-sound-detail-equivalent-to-the-6as7g-ecc230-6n5s/"],"source_urls":{"r_type":null,"tdsl":"https://tdsl.duncanamps.com/show.php?des=6N13P","radiomuseum":"https://www.radiomuseum.org/tubes/tube_6n13p.html"},"raw_equivalents":["6N13S","6H13C","6AS7","6AS7G","6AS7GA","6080","6080WA","6080WB","6520","CV2523","CV2984","CV10322","CK6080","E6080","ECC230","A1834","A4475","EI834","RK6080","6N5S","7802"],"equivalents":[{"type_number":"6080","equivalence_type":"direct","notes":null},{"type_number":"6AS7","equivalence_type":"direct","notes":null},{"type_number":"6AS7G","equivalence_type":"direct","notes":null},{"type_number":"6H13C","equivalence_type":"direct","notes":null},{"type_number":"6N5S","equivalence_type":"direct","notes":null},{"type_number":"7802","equivalence_type":"direct","notes":null}],"similar":[{"type_number":"5998","reason":"Same Octal pinout but approximately double the mu (5.4 vs ~2.5) and gm (15.5 vs 5.5 mA/V) — changes bias points, not a drop-in","has_detail_page":true}],"pins":[{"pin_number":"1","function":"Grid (triode 2)","function_code":"g1_2","notes":null},{"pin_number":"2","function":"Anode (triode 2)","function_code":"a2","notes":null},{"pin_number":"3","function":"Cathode (triode 2)","function_code":"k2","notes":null},{"pin_number":"4","function":"Grid (triode 1)","function_code":"g1_1","notes":null},{"pin_number":"5","function":"Anode (triode 1)","function_code":"a1","notes":null},{"pin_number":"6","function":"Cathode (triode 1)","function_code":"k1","notes":null},{"pin_number":"7","function":"Heater","function_code":"h","notes":null},{"pin_number":"8","function":"Heater","function_code":"h","notes":null}],"specs":[{"key":"Vh","display_name":"Heater Voltage","value":"6.3","numeric_value":"6.3","unit":"V","param_group":"heater"},{"key":"Ah","display_name":"Heater Current","value":"2.5","numeric_value":"2.5","unit":"A","param_group":"heater"}],"sections":[{"section_number":1,"section_label":"Triode","tube_type_key":"power_triode","specs":[{"key":"Va_max","display_name":"Anode Voltage (max)","value":"250","numeric_value":"250","unit":"V","param_group":"absolute_max"},{"key":"Pa_max","display_name":"Anode Dissipation (max)","value":"13","numeric_value":"13","unit":"W","param_group":"absolute_max"},{"key":"Ik_max","display_name":"Cathode Current (max)","value":"130","numeric_value":"130","unit":"mA","param_group":"absolute_max"},{"key":"Vhk_max","display_name":"Heater-to-Cathode Voltage (max)","value":"300","numeric_value":"300","unit":"V","param_group":"absolute_max"},{"key":"Rg_max","display_name":"Max Grid Resistor","value":"1.0","numeric_value":"1","unit":"MΩ","param_group":"absolute_max"},{"key":"Va","display_name":"Anode Voltage (typical)","value":"90","numeric_value":"90","unit":"V","param_group":"typical_operating"},{"key":"Vg","display_name":"Grid 1 Bias Voltage","value":"-30","numeric_value":"-30","unit":"V","param_group":"typical_operating"},{"key":"mAa","display_name":"Anode Current","value":"76","numeric_value":"76","unit":"mA","param_group":"typical_operating"},{"key":"ra","display_name":"Anode Resistance","value":"460","numeric_value":"460","unit":"Ω","param_group":"typical_operating"},{"key":"gm","display_name":"Transconductance","value":"5.5","numeric_value":"5.5","unit":"mA/V","param_group":"typical_operating"},{"key":"mu","display_name":"Amplification Factor (μ)","value":"2.5","numeric_value":"2.5","unit":"—","param_group":"typical_operating"},{"key":"Rk","display_name":"Cathode Resistor (self-bias)","value":"250","numeric_value":"250","unit":"Ω","param_group":"typical_operating"},{"key":"Cgp","display_name":"Grid-to-Plate Capacitance","value":"10","numeric_value":"10","unit":"pF","param_group":"capacitances"},{"key":"Cgk","display_name":"Grid-to-Cathode Capacitance","value":"8","numeric_value":"8","unit":"pF","param_group":"capacitances"},{"key":"Cak","display_name":"Anode-to-Cathode Capacitance","value":"3","numeric_value":"3","unit":"pF","param_group":"capacitances"}]}],"synced_at":"2026-04-07T12:26:49.193Z"}
