Attenuator with Holland Gibb Droll

[Alleycat]

New here so sorry if this is not the place but figured someone may know. I have a Holland Gibb Droll 4x10 (50W) that has a separate speaker/tube for reverb. It is a hot rodded B59 Bassman circuit from what I understand. Out of the amp are (3) 8 ohm speakers wired in Parallel via 1/4" jack. If my math is right this would be 2.67ohm? There is a RCA jack also coming out of the amp and through reverb unit that goes to a dedicated speaker. I am not a huge fan of the reverb unit so losing it and having a 3x10 cab wouldnt make much of a difference to me and usually run it this way with a delay pedal anyways. Amp sounds INCREDIBLE at 5+ with channels jumped but is VERY LOUD. Would like to add attenuator such as a hot plate but have been leery. I would think that a 2 ohm attenuator with it left as is would not cut the dedicated reverb speaker? Not an amp guy and would love some thoughts before i purchase a 2.67 ohm hot plate and be thinking wrong. Thanks for any help!

Show us a schematic

I have searched everywhere for one. Oddball amp. Everything I have read says it is a 59 Bassman circuit but I have not found a Bassman with dedicated reverb speaker. Pretty sure this was a Holland thing. Company is no longer around and very little info out there on them except they sound good.

Basically looks like this in cab. Not sure whats happening inside...

Looks like the only place I can put an attenuator is at the 1/4" jack to the (3) 8 ohm speakers. In doing so seems like it would only attenuate the load to those 3 speakers and the reverb speaker would be playing on whatever the amp is set at (un-attenuated) If I disconnect the reverb RCA jack at the amp and just use the attenuator at that location this should be 2.67 ohms?

Got my answer direct from Mike Holland today. Very helpful and full of info. He said the way the circuit is designed a 2.67 hot plate works great with or without the reverb circuit plugged in.
