B3 Tonewheel Generator Re-Cap
HTML-код
- Опубликовано: 11 ноя 2023
- My 1957 B3 Hammond Organ had lost all of the original brilliance over the years and was sounding muddier than the banks of the Mississippi, and re-capping the tone generator was the only option. I videoed the various stages of re-capping and although it's not very exciting, it might be useful to anyone contemplating doing the same up-grade.
I have a C-3 that desperately needs this, so your video is very helpful. Thanks. 🎹🎹🎹🎹👍
Thanks for your comment. Recapping the tonewheel filters is the one most effective measures in getting Hammond tonewheel organs back to factory brilliance. I'm sure you're a hot-shot with the soldering iron, but contact me if you want any tips or advice.
I owned a B3 that I bought new for many yrs. You cannot beat a B3 sound. It is a sound that sticks in your mind. I am always looking for that specific sound.
I got rid of my B3 because maintenance got to be very expensive here in NM. I scaled down to a YC 73 Yamaha. Love it. I do not miss the hauling around and storage and trying to get people to help you. But there is nothing like an organ sound of a B3.
SOLD IT TO A CHURCH!
Hi Carl, many thanks for your comment. I've been a life-long tonewheel aficionado and owned many models. I sold the B3 as I didn't play it much. It was dusty and dirty and sounded grim. Having brought it back to near factory electronically and cosmetically I sold it on to a young enthusiast and gave the proceeds to a child charity - the B didn't owe me anything. It was a wrench, but I don't miss oil dripping on the carpet and the smell of musty 1957 technology. There's a dearth of Hammond Tonewheel engineers these days and I was just lucky to be well versed in tube technology. I may get a Hammond XK5 combo - something I can shift around the house with ease. For me, owning a B3 was the primary appeal. Give my regards to NM.
Nice!
Amazing! It’s a dream of mine to one day own a b-3 with a leslie. Such a uniquely beautiful sound. It helps that you are an incredible player!
Many thanks for your lovely comment. I'm a life-long tonewheel organ aficionado so I understand your admiration of these instruments. I'm old enough to remember when the Hammond range of tonewheel organs were on display in Harrods and other top London department stores. Whilst I can take the credit for the well maintained electronics of the B3, credit for playing goes to its new owner, Bob Birch, who is an accomplished keyboard exponent. Hang on to that dream!
Fantastic restoration job followed by fantastic playing! Thanks for sharing!
Thanks for your kind post, Bob. Whilst I, with my well practiced modesty, take credit for the re-recap, Bob Birch takes a bow for his great playing.
Lots of thanks for sharing this video. ❤ This will remove my worries a lot for my 1963 A-100. She is still running smoothly, bur the day will come one has to replace the caps. .....and I don't think the local electronics dealers will go "Yeah, man, no problem, bring the thing around, we will fix it once we finished the LG OLED and the iPhone display from yesterday!"
Thanks for your comment. There's very few vintage electronics engineers around these days and even fewer people with Hammond specific knowledge. However, with a methodical approach, it's something the novice can attempt.
@@julianbonser I got the organ a few years ago (an absolute childhoods dream but even used too expensive for me), put it on a trailer and carried it through half of Germany to my home, where it would not play: Only thunder-like explosive sounds. The former owner had no idea, because it played well at his home. So I had to open it up and take a look: 1 tube broke during the transport, the rest of the inside looked just awsome, just like brand new! There was not even dust on any surface of the inside - I was speechlessly wondering. So I checked everything up and oiled her (the former owner warned me several times from over-oiling the instrument, which I know now is a myth). I poured almost 150ml of Hammond oil into her, my god, she must have been starving of thirst (and I was checking the floor all the time, because I feared the thing might leak in any way...)
Now I could hear the organ tones, but still with a lot of thunder.
Then I saw the only part which had to be newer than 1964, a plastic clip at the AC jack. The 1963 needs an external Voltage transformer to run in Germany with 230V. I pulled the plug and realized that the thing must have been treated with contact spray/switch oil or what do you call it for decades!!! There was a kind of sticky, dirty, crystall like, disgustingly looking cover around the metal contacts......
I sanded it down with a 40 grain sanding paper and voilá:
The A-100 runs as silently as the one in your video and plays and sounds beautifully now.
Thank you again for your detailed work 👍♥️
Very cool! Great when a player can repair their own instrument. Nice playing too!
Many thanks for your kind comment. I trained in old World electronics and it's great to redeploy these skills renovating vintage instruments and juke boxes.
She sounds beautiful man! She lives on. Nice work.
Thanks for your comment. I think the re-cap has wound the clock back to close on 1957. It was a labour of love but the generator should now be turnin' and burnin' for another 66 years.
Super stoked to see the original capacitors had the foil side marked, hopefully you followed suit when replacing them.
Hi Jorje - an astute observation. I used mylar / polyester type capacitors that don't have a designated polarity as their construction doesn't make them susceptible to picking up EM radiation. Thanks for commenting.
Impressive video. Thanks for sharing.
Would have rather heard some catholic music or some Phantom of the Opera
My dad was an organist for 60 years. Sadly he past 3 years ago
I remember as a child of 6 years old sitting in church at his feet watching him use the foot pedals
You should be using foot pedals for the base
Your comment was appreciated. Thanks for sharing memories of your Dad - you must miss him. Whilst I agree with your musical sentiments, the purpose of the recordings is to demonstrate the post re-cap brilliance of the keyboard tones, the lower notes not using an inductive/capacitive filter circuit. Best wishes from the UK.
