Hello all. I recently acquired some carver gear. An M500t amp and a TFM 35 amp. Looking for some direction on the M500. I understand it’s a dual voltage unit using low and high voltages on the rails. My issue is the relay doesn’t close upon power up. I’m leaning toward the op amp or something in that circuit. All the rectifiers check out good but I’m only getting around 30v on the low V side. Not the 40v it’s showing in the manual. The relay is good as I have supplied 24v to the coil to test it. I know these amps are different than most I’ve worked on but I’m ready to tackle this one. Thanks in advance for any input and I look forward to interacting with all of you. Cheers.

Hello all, My name is Douglas Thompson I am an ISCET certified electronics technician. I live in Tacoma Washington. I have been working on electronic gear for over three decades. I was teaching electronics theory at Clover Park technical College for over 4 years, and I was a field warranty technician for Carver for around 6 years. I still have and work on alot of these amplifiers every week. I am at the moment working on a pm1.5t that the entire fan assembly is missing, so I am trying gto find one to put in it.l

Newbee here,,,,, looking forward to learn what all this site is about. Had a Carver system 25 years ago ,,,,, now putting several Carver systems together for my own enjoyment,,,,, hope I'm not to late LOL🤕

Hi, I am the owner of Infinity IRS Beta as well as other Infinity speakers. I am contemplating Genesis II

Hey all! Thanks for the warm welcome! I'm working on four (4) systems, 2 have three (3) TFM 55's sledge hammers for the bang and umph, one has a CT-29V and the other has a CT-28V for directing traffic. The third has three TFM-45 high head room bangers, it has a C-16 for directing traffic and the purpose is to well,,,, see how it performs against the other two,,,, blame Roland for that lol The later is umm,,,, well and please don't be upset, is a bit of a hodge-podge to be honest. Basically its an old Toshiba mini system that's in the process of getting two (2) TFM-35 framing hammers fitted to it to replace the tired amps that came with it

"This couple bought a rundown abandoned house for $1.5 million and plan to make it their forever home: Take a look inside...While cleaning out the home, they found some of the original furniture, old photos of what the house looked like before, and a record player that was hooked up to speakers all over the house. Volkov found that discovery pretty exciting. 'Imagine having a house back in the day and you could play music everywhere in it from a record player,' he says. 'The record player was still there when we bought the house, so that was really cool.'" https://apple.news/AjoyndHDJQOms8_wEhzSNXQ 😎 🔊

Love this lady's drumming... she's a youtube sensation :). This cover of a classic song is pretty darn good. Love the vocals.

And for all the cat lovers ….

I checked all of the output transistors Q119-126 as well as Q118,119,109,110,116,117. All test good

Welcome! I found that Carver Silver 7t amps powered my Infinity Kappa 9's quite nicely. I've moved on from the Infinity speakers, but not the amps. Carver amps really like Polk and Infinity speakers.

Plinius SA-201 power amplifier, Infinity Kappa 9.2i speakers, Jamo Classic 10 speakers, DENON PMA-S10III integrated amplifier, Luxman M-300 Class A/AB power amplifier, a few Pioneer integrated amplifiers I started with, Wiim Pro Plus streamer and building up 😅

Welcome @BigB, glad you found us! Keep us posted as you put your 500 back in service.

if the relays are not engaging, your amp is likely in protection. Something has gone wrong. Suggest you start with downloading the service manual. Check the output transistors for shorts. Also check for DC offset at the outputs (up stream from the relays). This may help narrow down why its going into protection.

I remember the day and all the music we would listen to some needs help and show me how to set it up if any one is cool about the help at my house in eastern washington

With that TX-11, you will be able to pull in FM stations from miles, and I mean LOTS of miles, away. IF, that is, IF!, you get yourself an FM antenna. I have my internal home cable system connected to a big antenna in the attic, which pulls in FM from 200+ miles away. Probably get more reception, if I didn'thave 100ft of cabling, distribution boxes, etc, in the mix, but it works great for me.

Thanks Tim Now that's the kind of music you hear coming out of one of the rooms at an audio show!!!!

I mowed the lawn today, and after doing so I sat down and had a cold beer. The day was really quite beautiful, and the drink facilitated some deep thinking on various topics. Finally, I thought about an age-old question: Is giving birth more painful than getting kicked in the nuts? Women always maintain that giving birth is way more painful than a guy getting kicked in the nuts. Well, after another beer, and some heavy deductive thinking, I have come up with the answer to that question. Getting kicked in the nuts is more painful than having a baby; and here is the reason for my conclusion. A year or so after giving birth, a woman will often say, "It might be nice to have another child." On the other hand, you never hear a guy say, "You know, I think I would like another kick in the nuts." I rest my case. Time for another beer.
