}} with a {{B9A base}}. It is similar to the [[6CL6]] but rated for "on-off control applications involving long periods of operation under cutoff conditions", meaning that its cathode resists forming an interface layer. This is valuable even in always-on locations like the [[535]] vertical amplifier, where an interface layer would reduce low frequency gain. | }} with a {{B9A base}}.
