[rodgersorgan] Re: Rodgers 340 and its electronics/connections



Patrick,
Question #1 is what do you hope to "improve" by changing out amps?  As long as 
the S-100s are serviceable, I doubt you would see any improvement to the ear.  
The advantage of "modern" amps is that the modular IC packaging reduces 
manufacturing cost over the use of discrete components.  
It is very easy to make up an amphenol to shielded cable with RCA plug 
termination.  The shield goes to Pin 1 on the amphenol, and the center 
conductor to pin 2.
Multi-channel amps work equally to the task as long as the power supply is well 
designed and can respond to the power demand during "peaks."
Best regards,
Ed Wilson

Dear List: 

I have a Rodgers 340 Theatre organ with which I'm considering the purchase
ofa new amplifier for the speakers. 

I have two questions... 

1. The 340 plugs from the console and into the current S-100 amps are of an
amphenol style...basically a 5 pin plug system from the console into the
amp. 

If I was to buy a modern day amp, and I'm guessing they don't use the
amphenol type plug on present day amps, does anyone know if there is a
converter of sorts to use to go from a 5-pin amphenol into an RCA plug/jack
in the amps of today? (I'm guessing the modern day amps use rca type jacks
and inputs) 

2. Is having a single larger "multi-channel" amp with say, 3-4 channels of
output a better, neutral or worse set-up? (Each channel having at least
the100W each so it's equal to the S-100's from Rodgers) 

I'm trying to keep things simple and thought if I had only one amp with the
3channels I need for the 340 (Main, Brass and Tibia), it would be a simpler
all around system....but I don't know if I'd be compromising by doing so.
(Won't need the 4th channel pedal amp as my subwoofer is powered) 

Any and all thoughts and suggestions are sought here. 

Thanks and I hope everyone has a Very Happy Holiday Season!!!!!

Patrick Lane
