Vukodlak Productions- Hammond T-212 Power Amplifier

Ok... so this video covers a little more than just the T-Series power amp... I also goof around with the reverb tank and hammer out a few experimental notes on the upper manual with different switch settings. The tonewheel generator and Howard Industries 1800rpm self-starting synchronous motor both need some serious cleaning and lubrication. This is not only confirmed from the sound but just from the visual appearance through the oil access holes in the wooden partition. So out comes another TWG ;)

My hammond L102 makes the same sound that this one does in the beginning. What causes that? How do you fix it?

@MrKelmusic Flip the organ over and use a syringe to oil all the bearings, shafts, and springs... I recommend unsoldering the TWG and removing it however as this will allow you to give a thorough and proper oiling.

get an oscillocope and check the capacitor and grounds

Turned out to be the transformer on the vibrato recovery board... it has a 22V secondary and is almost impossible to find online for sale from an OEM...

I've since then won an entire cannabalized set of switch tab PCBs from another T-212 identical to mine, including my nightmare vibrato recovery board. I replaced everything other than the transformer on it as well (new and tested carbon resistors, electrolytics, and the power transistor). You're right, I need to get a scope BAD. Soon.

hahaha :))))) That "running toilet" noise is actually my aquarium... I have a pet aquatic turtle.... organ is nice and oiled now... working on the vibrato amplifier board...

Do you know what would cause the upper octave on the upper keyboard to have lower volume than all of the other keys. Also, do you have a service manual? I just finished oiling my T212, the TWG doesnt make ANY noise at all now!!!

I think that pot on the board is actually vibrato level. I think so, I could be wrong, but that's what it says on my H-182.

My organ makes that same goofy noise in the beginning. How did you fix that

[angie4josh]

that has nothing to do with it. it just needs lots of oil.

W.W.J.D? Fix the running toilet and oil your freakin tone wheels!
