Hammond Brite Foot

[bsco]

Hello everybody......I had a local church call me about their expression pedal...apparently the bulb was replaced before at some point with an in-correct one and the inside chamber where the bulb resides was all melted.,...I have a pedal from a Hammond Sounder and a Piper II and I was going to use one of these for a replacement....I noticed that the internal shutter is different and the bulb that is in both of my expression pedals use a 6.3V/2W bayonet style blub....I have no idea of what the original bulb is supposed to be in the expression pedal for the Brite Foot model......and there is a lever on the side of the pedal that when pressed with the side of your foot will move in and out......It is a leaf switch but I have no idea what it is used for...does anybody here have any service info on this?? Thanks to everybody and anybody that can help me out....
Cheers

There is no actual 'Brite Foot' model. Brite Foot was just a Hammond trade name for one of its 'easy learning' features. We'd need to know the actual model number - there will be a maker's plate on the organ somewhere, usually underneath the keybed or around at the back where the AC cord goes in. Or take a photo of the organ and we'll ID it from that. It will be one of the Japanese made 'Romance' series made from 1977 onwards, probably a 125xxx or 126xxx model. The Piper II is from the same era so there's a fair chance that the bulbs would be the same. You would need to double check that, of course, before putting it in. Was any damaged caused to the light sensor during the 'meltdown' as you might need one of those too.

The footswitch is most likely to be rhythm start/stop. Only the largest and later models had 'Pro Foot' where you could assign a function to the switch.

Thank you for the reply....The model number is 144122 and the serial number is C 71366.......the sensor looks ok just don't know what bulb it takes....and I can't find any service documentation or schematics on the net for this.....the bulb for the Piper II and the Sounder model that I have use 6.3V/2W bayonet style bulbs....

Some organs of this era use a #657 wedge base bulb, 28 [email protected] amps, such as below:

Not aware at this time of any metal base equivalent bulb.

Thank you for your reply...well if that is the case, and I install the bulb that I have in there, it will burn out real quick.....what I really need is schematics or a service manual or even a decent detailed parts list....

I was thinking you could follow the wiring back to to a connection point in the organ and measure the voltage there or if possible at the socket. This could be an alternative rather than ordering a $50,00 plus postage, service manual from

A 144xxx series organ is a bit later than I thought yours was. It's one of the 'Composer' series from around 1983/4.

I think kkeys has the right idea. Measure the voltage first and then order the bulb.

I just checked the manual and it indicates a GE657. However, the picture of the expression shoe indicates it's a bayonet type.
According to an organ lamp guide, for a bayonet version with the same 28v, a GE757 used by Baldwin would work as would a #1819 also used b y Baldwin and Lowrey.

Thanks for all the help guys.....the original pedal was sent in to me....I don't have the organ....if I did i would have measured the bulb voltage at the socket....anyway, the original bulb is a wedge style...the pedal that I own from a Piper II has the bayonet style...the reason why I had posted here was to see of the bulbs for both pedals were the same rating....if they were I could just change the sockets around....Looks like they will have to ship the organ in as I can't determine what the proper bulb is supposed to be....and they are a couple of hours out of town but there is nothing I can do about that......Thanks for all the help...you guys are great......
