Mills dance master amp
by Hans Minderman 10 Apr '26

10 Apr '26

Hi All, I’m finishing up a Mills Dance Master, I have it all mechanically working and I’m now ready to work on the amp (an MCP 1644 amp). I have a schematic for it from the manual but it is not very useful because the caps and resistors are only marked with the mills ‘mcp’ catalog number and not with the actual values. The corresponding parts list has the same issue with just listing the Mills catalog numbers and not actual values. I checked with Bill Bickers at Jukebox friday night but he does not have a schematic with values or a rebuilt kit either. If anyone has a schematic or a listing of the caps and the resistors and choke for this amp please let me know. Thank you for your help.

Help picking new speaker
by Steve Swaine 25 Feb '26

25 Feb '26

Hi Forum, Well I’m working on my “new” Seeburg 200C and it looks like I need a new speaker as the original appears to be blown - getting lots of base distortion that I don’t hear at all when connected to a remote speaker. I’m not a speaker guy, so hoping to get some help. I’m fine buying a new speaker rather than gamble on a vintage one, but I want to be sure I’m not going to damage anything in my system and get something that will sound good. The 200C uses the HFA1-L6 amplifier rated at 20 watts. The load impedance is “8 or 16 ohms” and the output voltage is “16 volts at 16 ohm output socket”. The maximum output power is 27.5 watts at 400 CPS with 2.4 volts input. The manual stresses that the total power supplied to all the speakers must be between 5 watts and 20 watts. Again, not a speaker guy - I thought it was ok to use a higher wattage speaker than your amp wattage, but many on-line sources say that the speaker wattage really should not be more than the amp output - especially for tube amps. The speaker specs say: - Dual, coaxial, permanent magnet type - Low frequency unit - 12” direct radiator - High frequency unit - Pressure driver with multi-cellular horn - Impedance (complete system) - 16 ohms I see a lot of guitar speakers on line that are 16ohm and are 20-25 watts, but they don’t have a lot of range - not sure I need that much, but 5KHz (which seems typical) seems too low. I’d really appreciate some advice! Thanks!

Connecting multiple Seeburg wall boxes
by M De Simone 24 Feb '26

24 Feb '26

Why can only 6 wallboxes be connected to each auxiliary power supply? I have a situation in a diner where they have wired 5 wallboxes together and another 10 together. They want to get it up and running but don’t want their walls torn up to figure out the wiring. Just curious as it’s probably done in case of 6 wallboxes being operated at the same time. This scenario is very unlikely in this case, so before moving forward with tearing up walls and fishing wire I thought I’d ask the group. Thanks, Mauro Sent from my iPhone

It sounds from your description that you connected the 70 volt speaker to the output for the cabinet speaker. The line going to the cabinet speaker is a regular 8 ohm connection, All (with usual disclaimers) 70 volt speakers are 8 ohms between the transformer and the speaker itself. Connecting that to the transformer of a 70 volt speaker will result in very low volume to that speaker. I'm guessing your speaker may have a loose internal connection to the voice coil, of that the cone is rubbing on something, but the best way to confirm that is to connect it to another amp and power it at the level at which is distorts and see what happens. > Any suggestions on speaker reconning sources?

Seeburg 222
by Jukebox Repairman 21 Feb '26

21 Feb '26

Years ago Ron Rich helped me with a 220 that was making a popping noise in the audio during scan. I'm having the same issue with a 222 and checked my notes but couldnt find what the resolve was. Anybody know what causes this? Its not the mute contacts. for some reason im thinking he said it was a cap but again i dont recall. Regards, Rick

How to replace seeburg motor mounts
by Steve Swaine 19 Feb '26

19 Feb '26

Hi Forum, Looking for help in how to do this. There are many videos on replacing the coupling but not so much for the mounts. The old mount rings look to be pressure fit on the motor and I’m not sure the best way to get them off without damaging the motor (or myself). I’m also worried about how to get the new ones on safely. The idea of whomping my motor with a big hammer is scary. I’ve seen that some replacement motor mounts are sold as the rubber part only with the instructions to glue the new rubber to the original metal rings. But my replacements already have the rings and if there is a safe way to remove the original rings then I’d rather do that then try and get the new rings off the new rubber without damage and the trust my glue job to put them on the old rings. Thanks!

Never heard "dark." > That's why I wanted to make sure I understood what you meant. No offense intended. No offense taken. I just meant lowered high frequency content as opposite of "bright" or excessive high frequency content. So, in other words, a reduced amplitude of high frequencies, typically starting somewhere in the upper treble. Not a hard low-pass cutoff, but more like a gentle roll-off or loss of “air,” sparkle, and edge.

Re: Stereo cart wired mono - what new, impedance resistance?

Fill me in a little. Was the "redhead" a ceramic or magnetic cartridge? And the cartridge you're using now, is it ceramic or magnetic? Configuration :: Load seen by each coil Normal stereo :: 47kΩ Hard-tied mono :: 23.5kΩ Resistor summed ~47kΩ (proper) > On 02/14/2026 3:29 PM EST Steve Swaine <steveswaine100(a)gmail.com> wrote: > > > Thanks! Yeah I saw that the redheads amps/preamps expect 47k, so was thinking for the stereo wired in parallel it should be half that. But I guess it’s just whatever sounds good? I did read that it’s important not to go too low (or let it drop to no load) or the cart can be damaged. Not sure if this is true. I’ll probably put it back to the 39K then. I recall it sounded fine - I just changed it because it was suggested that I restore it to what was in the schematic not appreciating that the stereo mod might make that not the best advice. > Thanks, > -steve. > > > > On Feb 14, 2026, at 1:31 PM, js--- via Jukebox-list <jukebox-list(a)lists.netlojix.com> wrote: > > > > It's not a hypercritical value.
