Just wanted to say a BIG Hello everyone! What a great community of Carver lovers I've discovered here! I myself have been a fan of Carver gear for many years, starting with a killer M1.5T that was my first "grown-up" amp! Next I played with a C-9 Sonic Holography machine. And, a owned a pair of platinum Amazings in gorgeous Piano Black. Well friends, my latest Carver score is... Drum Roll!...... A mint condition M1.0T! And by the serial number it seems to be a late production (non-inverting) unit. The Amp seems all original with not a spec of dust or any signs of heat or heavy use. It sounds great as-is but after reading all the stories of how fantastic it can be with the MkII Opt.2 upgrades, I've decided that I would like to take it in that direction. I have some experience in the DIY realm troubleshooting/fixing components and building a FirstWatt F5 last year. But, I am in no way an expert and will surely have many newbie questions along the way

Greetings and thank you in advance for any advice you may offer me. I have a pair of Phase Linear 400's and a 4000 preamp. The amps are in great shape physically, zero scratches, good lights and meters. Just gorgeous. I have not used them for years but I'd like to relight that candle. But this time, I want to use fuses inline to the speakers. The last time I used them, I had an issue with a volume spike which caused one of them to fry a pair of woofer voice coils. According to the local "stereo repair guy" (who actually does seem to know what he's talking about and has a thriving repair business) my condo's electrics were more the issue than anything. The wall which contained the power outlets went through the bathroom circuit and was constantly acting up. The speakers would make a pop sound when anyone went in and turned ON or OFF (especially OFF) either the light or fan in the bathroom, the speakers would hum when the fan was on, etc. Its been years but I remember various other electrical gremlins on that side of the condo, the wall plugs were intermittent, etc. It was his belief that the electrics were the issue and not the amp. He called it a DC transient spike or something that went right through the amp. So, I'd like to fuse protect the speakers but I don't quite know how. A few questions... 1. Is it a simple inline, automotive style fuse holder with a glass fuse? 2. Does it need to be soldered to the wire? 3. Fuse amperage? 4. One fuse for each speaker, attached to the + wire? 5. Anything else that I'm missing? I've got a big man cave over my garage and I'd like to get it thumping. I'm going to use a pair of Klipsch CF-3's and perhaps some Klipsch KLF-30's or KLF-20's. I have a few other options as well. ANY help appreciated. OM

Welcome. Since you are dealing with an AC signal, you can one fuse either Pos or Neg side, but most people choose Pos. To calculate fuse size, take the power (in watts), say 200, and divide by the speaker impedance (say 8 ohms), then find the square root of the result. 200/8=25, √25=5, so in that case I'd use a 5A fast blow fuse. You can use either ATC or ACG type fuses and in line holders.

Welcome! Try this for a starting point. 'Draw' a line from your speaker impedance across to the max power and find the fuse size. FWIW, I use 3A fast-blow in my Amazing Silvers.

I've found another excellent example of Sonic holography. LIttle Axe - London Blues. There are so many different influences here -- jazz, blues, reggae, hip hop (don't sneer until you've heard it). If you can find this in the bargain bin somewhere, it's definitely worth a listen. Here's a youtube link:

Welcome to the Site, Arnaldo. Great opportunity with that stock M10.t, to "take it to 'eleven'" when you MkII it. Glad to have you aboard. Post lots of pictures (it's easy). And enjoy the ride with OCCD.

Many thanks for the prompt reply and welcome. I addressed the electrical issue by moving! ?

Welcome Arnaldo, I also have an M-1.5t and M-1.0t. Love them both and use them to bi-amp. You will love all the resources and great folks that inhabit this corner of the internet and Audio world!

Welcome to the land of OCCD! Carter

Thank you Sk1Bum and Balok! Yes, I agree a refurb is definitely in order. Especially since I plan on keeping this amp rocking another 30 years! Just starting to learn my way around the forum and all the great info on audio in general.. not just Carver products. Guys, What would be a good starting point to start studying the parts and procedures for the Mkii upgrades? Is there a fairly current parts list or BOM for the M1.0T that someone could point me too?

WELCOME Arnaldo! Glad you found us....very helpful members here. The MKII opt 02 upgrade is a great way to go

Welcome Arnaldo. Congrats on the acquisition of the M1.0t. If it is 100 percent stock, then it is 30 years old and due for a refurb.

Hello Arnaldo, and welcome to thecarversite.com. We're glad you're hear. There is a lot of information here, much technical know how, and a pretty good bunch of folks that are happy to help. The M1.0t is a great amp in stock form. I have one getting repaired and getting the mk II, opt2 upgrades now. When you get the needed permissions and a chance, please upload some pics of your gear in the Members Systems area. We all like pics of all kinds of audio gear. So kick your shoes off, turn up the music, and welcome aboard.
