Re: UP dumble for sale
Heh, Aaron. I do amps full time. Off the bench, out of my working memory!
The Hotel Hog does not have a presence control. The Presence cap is hard wired in.
That pot on the front is a Master Volume. 1M-A works well there. that 50K RA pot needed to move.... move over Rover!

Re: UP dumble for sale
Looks more like a master volume for the Vibrato channel only?

Yes, the 220K mixer resistor is lifted from the board on one end.

Re: UP dumble for sale
Yup, I think that's it . The MV is before the BMish channel's 220K mixer, in parallel with the trem pot in question. I'm gonna move mine there and see what sort of difference it makes. I imagine it could be incredibly useful this way when using and a/b to switch...

Can you tell me how you know that is correct?

Thanks for sharing Jelle! I think I have an extra relay transformer laying around and a donor silverface in need of fixing up so I may have to try this....jelle wrote:It is like this:

Re: UP dumble for sale
Yes, very nice, thanks Jelle!

Obviously the layout is for a Twin, but if you omit the Mid on the normal channel it matches the pic.dorrisant wrote:Can you tell me how you know that is correct?
Seems a waist to use the relay to switch the reverb, it would sound nice used as a PAB.
Re: UP dumble for sale
I've peeked inside Brandon's Bludophonix and built one myself out of an old Super Reverb a few years ago. This looks very similar. I'd have to check my notes to see if exact.

Jelle, sorry for sounding rude earlier... Thank you very much!
mhartman, are you saying you built a UP? Or a Hotel Hog?

Seems like there ought to be a sticky in the files section to collect D circuit mods. Can anybody do that anymore?

Add the PAB relay and change some plate values and you are in UP territory.Aaron wrote:Obviously the layout is for a Twin, but if you omit the Mid on the normal channel it matches the pic.dorrisant wrote:Can you tell me how you know that is correct?
