Hello all,
I'm still a bit of a novice but have been fortunate enough to have restored
an AMI G-80 and F-80, so relatively the same in most respects but I'm
learning.
So here is my question. Is it possible to change the speed of the turntable
motor on a AMI D-40 Jukebox from 78rm to 33rpms? I don't know if that's
possible. Does anyone have any thoughts? I was hoping to restore my D-40
and play 10 inch 33 Lps on it. Please let me know if I'm just crazy or this
a possibility? Thank you as always.

Gentlemen,
I have been on this list for a long long time, have 4 jukeboxes AMI-C,
Wurlitzer 2700, and a Seeburg HF100R and an M100A.
I have just picked up a 3W1 to hopefully hook up to my HF100R. Looking it
over it looks like it only needs the glass dome and coin glass. Ordered from
Victory Glass.
I do not know much about Wall Boxes yet there is some information in my
HF100R Manual. Some Questions for the Group.
Looking for Gasket for the dome glass I see a set for sale for the 3WA 200
selection are they the same?
I am a little confused on a Stepper? Or is that a Wurlitzer thing?
Does the 3W1 just plug in to the selection receiver?
I will get into the manual as soon as I have a little more time.
Thanks for any help or advice you can share.

Here’s a fun one!
I have need to test a Wurlitzer 516 amplifier from a model 1500 but the jukebox is 2 hours away. I have a mech from a 1700 or 1800 set up that I use for testing amplifiers from about models 1800 to 2300.
The 516 amplifier uses an 11 pin plug to the amplifier as does say, the 530 amplifier from a model 1900 but when I compare the schematics they appear very different. Would anyone know if I can test this amp with this mech?
I do realize the 1500 uses a field coil speaker and I have an adapter for this purpose.
I just don’t want to smoke any components and am concerned.
Thanks,
Mauro

I have a Mills Do Re Mi that is without a selection (carousel) drive motor. I have acquired one but need help wiring it in. The motor has four wires (two of course for the AC). Any diagram or drawing directing me where each of these go would be appreciated. Ascott822(a)aol.com.

Well, I'm done with trying to eliminate this hum for now. I did have
some marginal success with reducing it slightly. I was pretty much
already done but I came across a few videos on youtube that showed
troubleshooting a ground loop hum. I put the amp back on the bench and
tried using a piece of wire to make a new ground path from various
points. One of these was to place one end of the wire on the ground
strap from the ground strap for the PCB to the opposite side of the
board near C17. That took some of the edge off the hum but did not
eliminate it. I decided to run a 16AWG wire from the strap to the pad
for the jumper wire near C17 and leave it that. Maybe some day when I
am feeling adventuresome I'll trace out the ground paths to see how many
jumpers are used to tie into the perimeter ground plane to see if I can
isolate and reground different points on the board. I will note that
there is one track for the heater circuit that runs parallel to the
ground for quite a bit of distance. The ground strap is at one end of
this run and the place where I tied the new wire is at the other end.
Other thoughts - I don't know if I am expecting too much here or not.
The hum can easily be drowned out with background noise and it is not
noticeable when music is playing. I just notice it in the time between
when the amp unmutes and the music starts. I'll also admit that my
bench testing setup is not the best for testing this due to the small
speaker I am using. There is a notable difference between a single 8"
speaker and 3 x 12" speakers when it comes to 60hz hum.
