Re: [hammond_zone] Replacement tube for Model M

The first tube on the left is a 5U4 rectifier tube. If this one went T_U, then I suspect you've got more serious problems elsewhere. Where? Start with the Electrolytic caps. The large can cap and any other bigger than a pencil cap that has a + mark on it somewhere. If you're not experienced in electronic repair work (and especially involving tube stuff), I'd take it somewhere. This stuff can killya, even after being powered down for a few days. There were a few different versions of the M-3 amp, older ones with an EM (4 wire) speaker, and the later with the PM speaker. Lars has some later schematics here: Hope this helps. pda Jax Fl. cahigg wrote: Fired up the M last night and saw a flash in the back when I flipped |

For reference, here's the Service Bulletin for the RC filter mod.

Goff and Hammond both recommended installing the new filter assy on the front (looking from the back!) of the TG's, but I found if you cut the wire coming from the TG just right, you'd have enough lead wire to install them per the factory install (on top of the Coil/Cap for each of the 12 notes) The pdf version.... If you can't see the pdf's, Marc has also scanned them into gif's.... Hope this helps, pda Jax Fl. Randall Bush wrote:

Replacement tube for Model M
cahigg
Fired up the M last night and saw a flash in the back when I flipped
the start switch. Blew a tube and now I need to find out what tube it is and where to get a replacement. If you're looking from the back, it is the first tube from the left (on the amplifier?) The only markings on the tube is RCA Electron Tube Made in USA 9-09. I thought I could find just about anything on the web, but I'm getting nowhere. Any help would be appreciated. By the way, I also have an M3 early 60's that has two Leslie half moon switches. How do I tell which Leslie model it's wired for? Thanks again, Chris Springfield, IL |

Re: [Hammond_zone] M101 VS C3
Hi Nick. I'm glad he tracked one down, I remember he said there was one in
Perth, they've quite hard to find in oz. I've still got to call him, and have a beer with him on day, he's a bit closer to me than yourself, he only works a couple of blocks away, and I'll get to go to one his gigs soon too hopefully. Out of interest, I was looking at a really nice B3 with twin 122 leslies on Ebay yesterday, they looked really beaut, unfortunately out of my price range, and a bit far away for me. I brought a Yamaha E70 last year for AU$600.00, and it's a nice organ, good sound and I thought the price was good considering they sold new for around AU$17,000.00 in the early 80's. I used to play a Hammond 122 when I was at school in around 1983, and it was a really nice sounding organ, and wouldn't mind buying one if I come across one for the right price, as its all about being in the right place at the right time.

Hi Nick,
Starting about 1964, Hammond included additional filtering for twelve of the tonewheel outputs. This consists of a capacitor/resistor (RC network) on the output of these tonewheels. My C-3 is a 1961. When I ordered my TG cap kit from Goff, I also received the components to add the RC filtering.

Lyle,
Another thought is the condition of things like TG capacitors. When I first got my C-3, I thought it sounded pretty good. I could not believe the change after I replaced the TG and vibrato line capacitors and added the RC networks. It was like a whole different C-3!

It could be that the M-100 has red mylar caps in the tone generator, and

the C-3 wax caps. This can make a fairly large difference in the sound. I have a few organs with wax caps and two with mylar caps, the two with mylar are alot less muddy and sound more balanced. Cheers Ron Bell. ----- Original Message -----

Re: [hammond_zone] Percussion on a T202
Michael Fulk wrote an article about getting 2/3 percussion out of an E-100, I
have a copy on the web. <A href="> </A> While both organs had the enhanced "pre-voiced" percussion, the E-100 has a tube vibrato/percussion, where a T-series is all solid state. Maybe Mr Fulk knows how ? His address is in the article above. Doug |

Percussion on a T202
vitesse67
Hi,
Somewhere (out there) is a quick guide to adding 2nd 3rd harmonic percussion to a T series. I have tried serching for it but no luck. Does anyone know where this elusive diagram might be? (answers on an email please) I had a reply to this question before but unfortunatly lost the link when my PC died. (Sorry) Thanks Hamm-monsters (what do you call a collection of Hammond nutters anyway?) Stephen vitesse@... |

Re: [hammond_zone] glass packs on a Leslie
Bro. Brian: I was just wondering how the hotrod kit sounded last night. I
wonder if one of those can be put on the 147 that I have with the RT-2? that is if I get the thing going???? The tubes out of the RT-2 are Sylvania, RCA, and KEN-RAD. Most of the nonglass tubes are RCA and one or two are KEN-RAD. Bro. Sam |

glass packs on a Leslie
Brian Williams
Hey everyone,
I got in touch with Steve Hayes a Speakeasy and he thought that the problem with our 122 Leslie at church was that the tubes wereworn out. Come to find out all the tubes look like they were 30 years old and they were all made in china. I bought an entire set of tubes off Steve and I also bought his Leslie Hot Rod Kit to see what it would do. The hotrod kit is a Peavey 80watt treble driver that is about twice the size of the stock Jenson driver. Needless to say. IT IS LIKE I PUT GLASS PACKS IN THIS THING.THe Tone is brighter and it is much clearer and Louder. Before, I could only put the volume at 7 max and it it was very scratchy, with not enough punch. I Now Can jack it up to 10 and watch the pictures rattle off the walls at the church. She is as clear and loud as can be. I think the church accross town caN probaBLY HEAR IT NOW. THe church could tell a difference too. There were many that told me the organ sounded good tonight that never said it before now. Some distortion still exits but to the true Hammond player that is desireable. Thanks Steve and everyone at the Hammond Zone, I wish you well with that rt-2 Sam. God bless Bro BRian _________________________________________________________________ Join the world?s largest e-mail service with MSN Hotmail. |
