I have two questions related to the need to recap. I am going to buy a W1-L56 Wallbox to use with my Seeburg Trashcan. I'm mainly concerned about the possibility of damaging the "unobtainium" transformer due to a failed capacitor(s). I'm also concerned about my Trashcan's Master Selection Receiver because I will be plugging in all the tubes back in that are needed for the "Wireless Wallbox" section of the Receiver. My philosophies are "If it's not broken, don't try to fix it", and "If you play with something long enough you will surely break it". So, to minimize "playing with it", can I simply rely on the fuses (I'm going to add one to the Wallbox) to provide protection against damage should a capacitor(s) fail? If a fuse blows, I'll recap. Or should I just bite the bullet now and recap both the Wireless Wallbox and the Master Selection Receiver? To my knowledge the Receiver has never been recapped. It has run fine for me since I bought it in 2018 and I removed all the tubes needed for the "Wireless Wallbox" section of the Receiver. Any thoughts, please. Thanks, Paul Humel
You can not apply old adages across the board. Look, this is 75 year old electronics. It was built along commercial standards that are a notch above consumer grade (mostly). At this point you are about 62 years past the intended machine service life. Be thankful of the fact that these are simple electronic devices which can be rebuilt and not full of LSI proprietary/obsolete components. DIY'it or have it done. The unit probably won't work properly without it.

To echo Rob in another way - you wouldn't attempt to operate a car that has been sitting for 75 years without an oil change at the very minimum... A capacitor change is the same thing - they had a SHELF life or five to perhaps ten years as per the manufacturers specifications. So they need to be upgraded unless you want to destroy the transformer. John :-#)#

I advise my customers not to plug their a box again until the amp is rebuilt. You are playing with fire. And it's not like I need the work, and rebuilding amps and such is one of my least favorite jobs to do when I could be doing something else I like. Tony

Thanks guys for the inputs. I was hoping for an effective shortcut to avoid having to recap. But you make good points. I should be glad that there are no printed circuit boards with obsolete surface mount devices, etc. I had the Amp rebuilt in 2019, but was told no need to rebuild the Receiver at that time because the Receiver wasn’t using the Wireless Wallbox circuitry and could just pull out all the tubes. In 2023, I now have some experience, having used my Solder Sucker and solder gun to replace components in other vintage electronics. So I’ll just bite the bullet and do it myself. With 17 caps to replace, it won’t be a lot of fun. But, to use another old adage, I’ll sleep better at night. ;^) Paul Humel -----Original Message----- From: Tony Miklos via Jukebox-list [mailto:jukebox-list@lists.netlojix.com] Sent: Thursday, August 24, 2023 3:56 AM To: jukebox-list@lists.netlojix.com Cc: Tony Miklos Subject: [Jukebox-list] Re: Two questions related to the need to recap On 8/23/2023 9:00 PM, John Robertson via Jukebox-list wrote:

I was dubious of that advice, which basically said thatno capacitors in the selection receiver would receive power withouttubes. *Something* with a capacitor must be getting power inthere somewhere.
Without a schematic in front of me I can't be certain, but most likely it has a 5U4 or other rectifier tube and with that pulled, there is no higher DC voltage (350 to 450volts). The only power going to it in that state would make it safe to use without being rebuilt. Tony On 8/24/2023 10:43 AM, David Breneman via Jukebox-list wrote:
