Welcome! I remember the AP1800. If I recall correctly, it had 3 phono inputs and switchable capacitance and sensitivity. A capable and nice unit.

Welcome and congrats on finding a TFM-35!

Welcome! We're all looking forward to some pictures when you have an opportunity.

Welcome!

Welcome @matts2179! Often a steady hum indicates some failed components in the power supply portion of the amp. So it sounds like your Sunfire amp needs some service help. Two good service options for Carver gear include Nelion Audio (https://nelionaudio.com) and Carver Audio Repair (https://carveraudiorepair.com). Both of these shops are very well versed in Carver & Sunfire gear. And if you're just looking for some tech info, we have many service manuals and schematics here on our site. Click on the 'Manuals and Specsheets' link at the top of any page. I'm not positive about the specific sub you have, but there are quite a few listed there. Lastly, a search here might get you some hits on other owners that have worked on your particular model.

Welcome! The good news is that most quality vintage gear is serviceable and can be restored to as-good-as-new (or better) condition. Let us know what you have or are looking for and we'll try and help you out.

Welcome! If you're a Carver fan you are in the right place. Do you have any Carver gear at this point or are you looking?

Welcome - a pretty sweet collection of gear! Looking forward to some pictures.

Welcome!

Very nice - that amp was pretty crusty.

Welcome! The fan on your PM-1.5 should run continuously although very slowly at idle. It will ramp up in speed quite a bit when the internal temperature of the amp rises. At 50C it will sound like a jet engine is running. But of course, if the amp is that warm the music should be so loud you'd likely never hear the fan 🙂 If the fan isn't running at all it might simply be clogged with dirt and a good cleaning could get it back into operation. Or it could be burnt out and require service/replacement. The good news is that these amps are all serviceable. There are some owners that run these amps without the fan (to keep the noise down) without any trouble although likely not at extreme power levels. And some others have replaced the stock fan with a small computer type-fan that won't supply as much airflow, but is much quieter and will keep air moving through the unit. If you search here you should find some good discussion about both options. And if you're looking for repair service, get in touch with Nelion Audio at https://nelionaudio.com/

Pretty nice

I'd start out by downloading the service manual for your ALIIIs - click on the 'Manuals and Specsheets' link at the top of any page and scroll down into the speaker section and you'll find it. Then try a search here and you should find some info about service/restoration work other owners have down with their Amazings. That may give you some good ideas. Looking at the schematic, I'd suggest focusing on age-sensitive items like capacitors and pots. I'd also take a close look at the fuses and their holders as those can build up oxidation over the years and may need cleaning or replacements. Large power resistors rarely go bad, but it wouldn't hurt to check them to make sure they are within spec. Same goes for the chokes. It would also be worth looking at the binding posts to see what kind of shape those are in. Again, over 30+ years they can develop some oxidation that should receive attention. I'm not sure of mounting space, but those might be a candidate for replacement with some Speakon jacks. I personally dislike binding posts for audio equipment.

Welcome @FThumb! If it were me, I'd replace the surrounds if they are at all suspect, but I wouldn't try to outright replace the woofers. Finding replacement drivers with the same or close T/S parameters would be challenging and you don't want to change the performance of the originals. And regarding the crossovers, if these were my speakers I'd replace any aged components while I had it pulled apart. If you dig into them, post some pictures in a new thread as we all enjoy watching work-in-progress.

Really sweet. The gold-plated ground screw is a very nice touch.

If it were me, I'd send Speaker Exchange an email with a few pictures and see what they think.

Very nice - I like keeping stuff off the floor and shelving like this is a perfect way to do it.

As @Rob and @wrf pointed out, there shouldn't be too many problems re-coning a second time - assuming whoever did the job the first time didn't do anything crazy like using weird glues or damaging the cone. But even then, you could do a complete re-cone, if needed. If Midwest Speaker can't help you out, also check The Speaker Exchange (https://reconingspeakers.com/). They can repair pretty much any driver in any condition.

Welcome! Sorry to hear about your equipment losses, but the good news is that there are replacement pieces out there - and almost all of this vintage Carver gear is serviceable. So hopefully you'll be able to get back to where you were before too long.

Welcome! Lots of good info here about the TFM-15 you'll find with the search function. And the good news is that all these Carver components can be serviced to as-good or better-than-new condition.

Very cool. Don't often get many scores like that in life. Do you already have a home theater setup it will be used with?

Welcome!
