Fender Normal Channel design ??

[backline]

Yes I'm new to this place, nice to meet everyone.

So I did a Vibroclone from a Bandmaster Reverb 10 years ago. I love it but now would like to do something to the Normal channel. I have searched and looked at Dumble Heaven schematics and cool norms stuff which is the same except for the deep switch on the Bass that cool norm has.
Are push pull pots with a dpdt on the back rated at 1/2 watt and pitched mainly for guitar, Bournes going to be OK?

And on coolnorms.pdf, the last page has a deep switch, is that in addition to the advanced design complete version I can do?

It already has a factory hole in the chassis behind the normal channel from some mid 70's hum balance I ripped out,so I can put a mid pot there..

Well unless someone wants to cough up a Ultraphonix schematic.

yes those pots are ok.
do ya really need a deep switch,on my pro reverb I took out the #2 input and installed a 3 position rotory switch for different cathode bypass caps 25uf,5uf and .068uf. As with most Fenders playing above 4 the bass is too much for soloing and on the edge for clean also.
On my band master I put a mid control for both channels in the rear due to the holes being their from a former mis guided owner, you will be fine, just use sheilded wire.

Thanks Steve,
The thing is pretty bassy, has a jbl d130, so just as soon not bother with the deep mod.

I ordered the stuff I need. Maybe I will like the normal channel. The reverb doesn't sound near as good as my 69 super reverb's reverb. Maybe I will look at that, could be a lame tank. I really saw first hand what a difference from 69 to 75 was as far as parts and quality in workmanship.

In most old, and even some new reverb tanks the solenoid / coil will be loose on the iron core.
They should be solid in place or the can not transfer enough vibration to the springs for good reverb.
If this is the case get some gel type super glue and let it flow into the gap between the solenoid and the core and the verb will sound better.
While you are in there place a nice blob of silicone sealer on the wires where they enter the solenoid as thats where they always snap off from sonner or latter.
Of course if its not the right tank I am not sure it would even work without the 8 ohm input side.

Well I guess I can take a look at it. Never have opened up a reverb tank so it will be a first. Let me take a look at it and get back to you on it.
Thanks!

Sure enough they were loose with one I think the input very loose.

Done Deal! That is one sweet fix for a fender reverb tank. Thanks Steve! Who taught you that?

I will give the silicone overnight to dry but the coils are now snug!

Excited to hear it!

If you have the right Fender tank the input side will meaure about 2 ohms, and the output side 225 or so.

42 years of doin this stuff and some 25 years ago having 3 reverb pans fail in a years worth of gigging will in another Man`s words" necessity is the Mother of invention"

Also note that if you wire up or use a Fender foot switch, if you do not have the RCA cable for the reverb on/off plugged in you will not have the needed ground connection to turn the tremolo on.
Injoy my friend!
