W532 scratchy sound
by M De Simone 14 Nov '23

14 Nov '23

Good afternoon, I have recently been working on a Wurlitzer 532 amplifier and caps have been replaced and a couple of resistors that were out of tolerance. Tubes are all tested good and verified by swapping individually. The amplifier puts out good volume with defined bass and treble. The issue is that there is a slight scratchy sound in the high end of the spectrum. If I turn the treble to the lowest setting it masks it but anywhere else I can hear it if I listen closely. Before I blame it my test setup is like to ask, could the pec1 or pec2 cause this, as I have not replaced them? Let me know what you think. Thanks, Mauro Sent from my iPhone

Wurly 1250 selection problem
by Dean Carriveau 13 Nov '23

13 Nov '23

Hi all, My Wurlitzer 1250 was working perfectly and then refused selections when any of the twenty-four selection buttons are depressed. I checked the coin grinder and it runs, accepts coins and 24v goes to the make selection light so I know that transformer is good. I've been looking at the schematic and at a loss of where to begin. I was going to pull the junction box and and check the 24v transformer but it is supplying power to the selection light. Any thoughts? Dean

Seeburg STD4 Color sheets
by Jim McClave 10 Nov '23

10 Nov '23

How do you remove the front door color sheets on a Seeburg STD4 ? I have taken the top metal rail off for access. Looks like they should just pull right up? Mine are stuck and trying not to force them too much. I have a feeling they are original and have gaskets , etc have hardened. Any one else have this problem? Jim

Hi, with the details in the discussion that you suggested here https://jukeboxaddicts.proboards.com/thread/3712/seeburg-100c-cancel-any-pin I was able to deeply understand the sequence of contact closure and understand where the problem was (it was not so clear from the manual): during the C contact closure SC should still be closed for a short time in order to provide path to ground while in my case this was not happening.

Audio Question

I recently swapped out a defective Astatic cartridge with a Pfhansteil P51 on my personal 1015. Since the swap the audio seems to have lost a lot of low end and sounds “tinny.” Years ago when I restored it, I had added a Bill Bickers upgrade to the volume control box to improve the bass response. Obviously I’d like it to sound like it did before the swap.
