Well, I finally got it fixed! Thank you to everyone that offered advise, as that is exactly what I was looking for.

I removed the power supply transformer and opened it up. It was rusty and did...

Dear Forum members,
I am searching for a used, or reasonable priced, EXP-100f pedal for a church install of the XK-2. I have already found the Leslie 1122 to tie it into a fullsize Leslie 122, and...

Okay. I have gone through 8 more 2 amp fuses, and am pulling out my hair. (I am completely bald, the profile pic is my dad)

I found that the green wire was missing from pin 6 of the 6550's to one...

1. No, this amp is a 122, and I have added the 8 ohm resistor to the rectifier circuit as I have seen in some of the newer 122 amps, and also 122A, and a 147 on my bench at this time.
2. I do not...

It blew the fuse quickly with the new can cap, and brand new TungSol 6550's. All tubes were present, tested on my Hickock 6000a, and all new caps and resistors wear spaghetti insulation on the legs.

Here is the schematic of a 122a amplifier showing the 8 ohm 5watt resistor in series with the rectifier bridge.

Yes, the fuse blows right away, as i am bring the...

Here's more.

Dear Forum Members,
I have just finished my fifth total rebuild of a 122 amp, and this one is popping the fuse when I bring up the voltage on the variac. I disconnected the red wire from the...

WOW! Looks great! I am very interested in making a chop version also. But the question of how to hookup the gas pedal arises. If I use a trek solid state preamp, does that use a different combo style...

WOOHOO!!! Thank you! I have been looking everyday. Thank you for the extra pair of eyes!

I am searching for a necklace reverb for a Hammond Pr-40 I am refurbing. I have completed re-capping the ao-32 and ao-33-1 amp, bolted in a pair of EV-15b drivers, still have the 12" OEM's in there...

Have you removed the necklace reverb from the cabinet? Lay it on the table and research why the clamps will not open. Rust, binding bits...? An obstruction?

I mounted an EV15b speaker in my PR-40...

My dad bought a brand new B3000 in '78 when we moved back to Alaska. He said he wanted more sounds as a solo entertainer/organ grinder and that this new organ would be more reliable. Dad's uncle,...

Just asking a dumb question: Did you thoroughly shift the buss bars on both manuals?
And about the reverb: Did you check the rca plug and wire going to and from the tank? I understand that they...

Thank you for the reply! My interest was also to expell the extra heat of the rectifier tubes. Also, to simplify things. But if there is no valid comments here in using the Solid state substitutes,...

Yes, quad cap. I agree with replacing all of the B+ resistors and also anything else questionable.
Yes, I have many parts on order from Rick at tonewheelgeneralhospital and I plan to re-cap both 47...

Here is the damage on the AO33-5.
Thank you!

Hi! This is my first post so please be kind.
I have been servicing Hammond TWG organs here in Alaska for over 30 years as a sideline, but the calls are coming in faster now than ever before and am...
