Need help on schematic

[Mr.Woody]

Hey guys, looking to figure out understanding what the middle tube of the 5 does. i'm assuming it's reverb. my question is if i pull it out what will happen

Here's the schematic

Thanks,

[The Dirty Tube]

V1 = preamp
V2 = preamp
V3 = reverb
V4a = reverb
V4b = tremolo
V5 = phase splitter
V6 = power
V7 = power

Yes, if you pull out V3, no reverb. If you pull out V4, no reverb + no tremolo.

so, it won't hurt anything to just pull the tube and leave it out? I've already taken out the reverb tank and don't plan on putting it back in. Just figured i could use the tube somewhere else since i don't have many.

Thanks for that by the way

You're correct. That'll work.

 

[Mr.Woody]

oh, also, if i pull out v3 and v4 there is a very noticeable drop in volume, any thoughts on that?
