B3 and 147 troubles

[geoffbrown]

Just for comparison purposes, even though the 147 is meant to be brighter than the 122, I cant hear any real difference, they both sound the same to me

Both amps have had voltages checked, can caps and crossovers replaced etc

Using the one half moon to speed switch both leslies while still using the six pin connector kits sounds difficult if not impossible

Hey Geoffbrown.

Just to be very clear. In the a100 I have the kit to convert the signal to and for the 122 hey but the setup for the 147 is so much easier don't need a kit And the driving ac is from the mains. the only thing I need is the gnd and the red G ANd I have already checked out with Wes that the switching high and low speed can be done. on one half moon

[geoffbrown]

Yes thats how my 147 is connected to either the C3 or M100, but I dont use a halfmoon for switching the 147, I use 3 position switch slow stop fast

That would be real nice to have I like the sound of the stopped drum but it is not a must have at this point . on my a100 I have the MEE switch so if I use the back side for the 147 signal .. wonder what options I would have notimportant to answer I'm just dreamin

Ok I now have the a100 bright as usually playing through the 147 at the same time as the 122. Big thanks to Enor here for getting the wiring straightened out. Now I can really tell the difference the 147 is even brighter and louder more punch than the 122 I like the sound cause I can temper it when I want softer. OK so the reason to do this was to make sure that I have a good testing platform to judge the 147 I have that now. And it is like you would expect Just how much louder should the 147 be than the 122?
Can any one provide some volume numbers say between the two Leslie's so I can tell if I'm in the ball park. Example : like 122 needs to be on 6 when 147 is on 3 to hear them balanced etc?

888000005 to the mat on console and 'dimed' on the Leslies? With C3/perc soft fast through this 147 on chorale? 888000008 same organ through 122.
Yes this 147 is in fact brighter.And louder.All 8's? Still prefer the 122 with this registration.

However,once onstage with a few 'rocking' guitarists all bets are off.Out come the 147's........both are great boxes AND HAVE UNIQUE characteristics.
147 has more 'headroom' in a live performance situation with multiple instruments,122 has as much or more great 'tone' but it breaks up earlier on 888800005.
Similar and yet different,also no two consoles the same.....YMMV?
This 251 has more iron than either and is the cleanest loudest tube Leslie amp in my 'gathering'.

thanks Pete think maybe I can test against your numbers but maybe when wife is out of the house. then perhaps I can get to the mat. going to keep a copy of this. so Far with the comparison I can really hear the difference in the two units. Sound on the 122 is really round/softer/smoother I 'm trying to find adjectives to describe the sound compared to the 147 brighter/ louder/ top end notes. much clearer etc

OK so now that I can hear the difference between the two leslies and figure that with the updates I have made to the 147 leslie (with the exception of some of the resisters) When I play the B3 with the 147 I have an issue with the tone. I get all the notes but not the crisp tones that I have in the a100 . It should be the same correct? ( with the exception the reverb) So this is leading me to believe I have more of a problem with the Pre amp still. I have only replaced less than half of the kit supplied - so I will do that cause I have them but also because there is an issue (as above)
The incredible brightness that I have in the a100 is due to the fact I trimmed the TWG with capacitors to peak it's performance and it really does show. the B3 has the ruby red caps that usually are not changed. I am planning to leave them for now - do the amp and other systems The work on the 122 hook up to the B3.

I never play that loud at home.That's what the 'warehouse' is for. And the rigs sound great in that space.
Same with sound reinforcement,must have a test site away from gigs.
At home its 90% headphones....speakers are little 6" Wharfedale Diamonds,amp is an old Luxman 707II.
Separate bass and treble controls per channel,20 real watts RMS a side.
Loudest amp here is the AO39 in the A102.....with less 'watts'.
Our old Sansui AU717 is way too big for this space,shame because it's been recapped and is top quality IMO.

The Leslies get a real full blast shakedown along with the consoles before they leave for work.
Last night the 251 box (with a cleaned up 147 amp) made less mechanical noise than my 'allowable',and got the call.
In a live streaming studio audience setting I don't want any issues.Time to perform.
The P15LL recone (kapton former) and the hardwood speaker baffle(1964) are a potent combo for bass.
Typically a stage Leslie is dimed,and the operator uses discretion in the use of the extra 'dynamic range'.
I certainly hold something back for the 'finale'.

Awesomeness........march on!
Are you doing bass in the left hand? or on the foot board

et you know how the work on the B3 pans out,
