Greetinghs to the List, Does anyone have a scanned copy of the schematics for the Rodgers S-100A (with the Bass Boost) and D amplifiers. All I have been able...
Hi, The crackling you describe seems to be similar to what our Rodgers 320 was doing. It turned out to be faulty preset level potentiometers , a squirt of...
Hope all had a good weekend, Has anyone "modified" the S-100 s to increase the freq response, if so what were the changes. I hate to reinvent the wheel. Thanks...
Hello all, One easy way to isolate speaker hum is to unplug or disconnect signal input at power amplifier. This should be quite easy to locate. If you still...
Good morning Frank, and list . . . I'm repeating what I was told by "knowledgeable others" here, so please don't shoot the messenger! If you are using your...
Hi List, Have any of you tried to improve the "attack" of the posthorn on your Rodgers 340's? Like most of them, mine has a bit of a funky attack that seems...
HI Bob, You make a good point, yet it seems that Ian was using somthing other than the S-100s (If my recollection is correct). I may shelve that idea for a...
For a Rodgers 340, I would be interested in knowing if anybody has found a way to improve the Tibia which is already nice. Also, what about the standard...
Hi, Bob. Are you running an H1 horn on the brass channel? I've heard, but can't confirm, that without the H1 horn, the post horn never sounds right on the 340....
... found a way to improve the Tibia which is already nice. Also, what about the standard speakers that come with this organ. Can they be improve without...
Hi Charlie, I'm not running the H1, but am running paralleled Walker TP3's which certainly do a wonderful job on Walkers and on the Rodger's Trumpet. Bob ...
Hi Jim, I have done two things to the Tibias on my 340. The first was to add some capacitance at the preamp stage to avoid the "roll-off" which the native...
Hi Frank, I did check out your red book which shows a custom posthorn and it is an entirely different animal built on a different ROC board completely. I ...
This discussion has been very interesting. My 340 is still stock. I did add two LaScala's to the organ and will try one on the Tibia channel. I have an MW7F...
Mention has been made in possibly replacing the Rodger's speakers with LaScala speakers. I hear these are quite expensive. Would some of you guys who have...
My instrument came with 4 LaScalas 3 W-13s and a P-32. This was another "custom" and the tonal designer was Jonas Nordwal. The tibias sound good through the...
Hi Bob and list, The reason that your Posthorn has ended up as it has is most likely becuase you haven't changed the keying voltage. As we discussed off list,...
Hi Bob and list, Bob Walker told me that the issue was in the stand up preamps. But his changes increased the gain too much for my liking (but that change...
Now THIS sounds like a VERY interesting Posthorn. It SHOULD be MUCH better than the standard issue. Interesting, Ian ... __________________________________ ...
La Scalas a wonderful speakers. I purchased two to add to my complement of 340 audio. The Trumpet (with its own generators) sounds fabulous through its own La...
Ian, Then the best bet is to look at the stand up preamps for a little help on the treble end? About the H1, as we talked before I don't have one but I do have...
As far as the P-2 goes, one test we did was when we took it to the Plaza Theatre (2500 seat atmospheric) in El Paso for some fundraisers. The 32' could be...
Frank, Those crude resistor/cap arrangements were better for treble lift. I will find the values and post them. I also get a lift from the higher keying...
I got very lucky on eBay. Someone was selling a small Rodgers classical organ with two LaScala's. I expected a bidding frenzy but it did not happen. Anyone...
Hello all- Last night I had the organ apart. I am getting 60 cycle hum from the Tibia channel, and a crackling (sort of like someone softly crumpling ...
Shane, Is the crackling constant or only when you move the expression pedal? Bill... Subject: [RTOU] Crackling and 60 Cycle Hum from Trio 321 Output Chassis? ...
Thanks for the reply, Bill. The crackling is constant. I have not noticed if it is greater or less at full expression pedal (expression pedal movment doesn't...
... From: Ian McLean To: RTOU@yahoogroups.com Sent: Tuesday, October 11, 2005 12:01 AM Subject: Re: [RTOU] S-100 Amps Frank, Those crude resistor/cap...
Hi Ian, I did try a slight voltage lift with a bit of improvement, but ultimately decided to forgo the permanent changes and went back to a rock solid 12.5 ...
