}} with a 6.3 V, 0.3 A heater.
<br />
The '''12AL5''' (European type '''HAA91''') is the same but has a 12.6 V, 0.15 A heater.  Both have a {{B9A base}}.
 
The 6AL5/12AL5 serves as the "disconnect diode" in the timebase circuit of many tube-era Tektronix scopes starting with the [[511]] in the 1940s and continuing through the 1960s in sweep plug-ins such as the [[3B2]] and other plug-ins such as [[C|Type C]] / [[CA|Type CA]].
