thats the later model choke, about 70 or 71 up. it should have a value of 1.5 Henry, the last one i popped onto a meter said 2.74 K ohms dcr.
i talked to Dan Torres about those and he told me they were a hangover from Gibson amps and rated about 400V. i don't know anything other than what he said and that just might be his opinion. the chokes he sold me don't look anything like that and are certainly rated at far less V.
