1978 Rodgers Repair Issue

[Rohrie2]

Hi everyone,
Does anyone have any 70s electronic know-how? I have a 1978 Rodgers in my house that I just moved across several states. We installed it in our home, and hooked everything up and it worked! Then we attached the pedal board, and all sounds stopped. We removed the pedalboard, and it's still not working.

The lights turn on, and so do the speakers, but neither the keys, stop tabs, or the pedals make any sounds anymore.

We checked the input and outputs for the speakers and we changed the transistor/amp; the speakers are working, so I don't think it's a transistor/amp problem. It might be a power supply problem?

Any suggestions? None of the organ repair places in our town seem able nor willing to help...

Thank you in advance for your feedback. :-)

Check fuses. What is the model number? Rodgers used a fuse holder on some models of that era that have a rectangular face, and you press it to pop-out the fuse. It may be that in moving the pedals that got jarred, and it popped out by itself.

From what you describe it's probably a simple mechanical issue. Most electrical problems would not make the whole organ dead unless it's in the power supply.

Congrats for lugging that old Rodgers with you! They'll never make another one like it, ever again, so we need to cherish these old wood and plastic boxes.

Have you tried a few sharp, strategic blows with your palm? That used to work on large electronic devices. :)

Perhaps you lost the 15 volt power to the amp relays. What is the organ model number, and are the speakers in the console or in external cabinets?

Sadly, this tried-and-true method did not work! Thank you for this albeit practical suggestion. ;-)

Like John said, listing the model number and the configuration of your speakers (internal, external, external amps?) would give folks here something to go on to help. He have some real organ techs, like John and Toodles, watching over us.

The less we know about the specifics the less we can help!

The Model Number is Scarborough 110.

Does it have a "Entertainment Center?" That's the headphone & recorder connection panel.
If so is the "Balance" knob pushed in?

And if does have a headphone jack, have you tried listening through headphones?

As I recall, the 110 organs were available with either a two-channel internal amp and speaker setup, or with up to four external Rodgers S-100 amps, each driving a speaker cabinet.

What is your particular configuration, as far as speakers and amps?
