Does PS-100 use 12AX7 or 12DW7?

Stage & Studio Power Station PS-100

Are these supposed to be running 12ax7 or 12dw7? I always thought 12ax7 after getting mine back from service there was a 12dw7 in there I’m sure that’s correct since that’s what you guys had left/put in there thanks.

(The PS-2A uses a 12AX7, so take care).

The earlier revision uses a12AX7. The later version uses a 12DW7.
We updated yours to a 12DW7 during the repair procedure.
