Hello everyone, I am a retired electronics design engineer who designed mostly digital and embedded microprocessor designs with a smattering of some analog circuits along the way. The Carver PM-1.5 is quite the challenge. I bought it many years ago and it worked well until the large power supply capacitors failed. I replaced them and it worked for quite a while longer and failed some years ago. I removed the dual power supply caps and found they had failed which is at least part of the problem. Now I am looking at sourcing replacements for them ( I have seen the EBAY replacement board with 4 caps), but I will probably make my own. Then I will see what else is wrong with it if I am able to . I appreciate any suggestions along the way. Especially how I can isolate my digital oscilloscope so I can use it to safely view wave-forms should I get that far. I have a Variac specially for this, but have never had the issue of needing to also isolate a 'scope to make measurements. Ways to do that would be greatly appreciated and thanks ahead of time if any one out there has the way.

@sea, here on The Carver Site, may not check here daily - but can also be found via a DM on Facebook, look for "Ed Atkins" Super great guy, and is the only go-to for ribbon repair for Carver amazings that has the correct jigs required to re-assemble them, holding the powerful magnets in place..., it's not possible to reassemble without the jigs.

Welcome. I messaged sea a couple days ago about my silvers (3 woofers). I'm having a buzz out of one of my 48" ribbons at certain frequencies. After reading through a bunch of threads it seems he may be our saving grace.

I am looking to see if anyone knows an easy way to get the tweeters working on the carver amazing speakers. I think i have tje silver series as I have four woofers in each and a single ribbon tweeter.

Just bought Boards of Canada new album Inferno .

@Roland gs - I have a pair of ALS III’s that started to emit a buzz, about 14 years ago or so. I got a rebuilt pair of ribbons from Ed (on exchange) and they have been excellent ever since. It is well worth the money. I also rebuilt the crossovers (new caps only) more recently after confirming a couple caps had failed.

I have downloaded the 360 SM from our site several times in the past. From this post in 2025 you can see the listing.

Scan it, save it to a pdf and attach it to a message. One of the Admins will take it and add it to the collection. Thanks for offering it up!

Sample Carverfest t-shirt has arrived, and it's not too shabby....(pay no attention to the elderly man modeling it...he's kind of an attention hog from what I understand). I'm working on a few other options for Carverfest, too. Thanks to those of you who have given me more ideas. An online 'store' will be provided soon where you can order yours .....along with a lot of other "fun" Carver and Audio related merch I've imagined. I'm using a 3rd party ("Printify.com") to handle all the making, selling, distributing of the shirts. Costs will be low. Any proceeds above the store costs will all go toward supporting the operating costs of the Carver Site. Stay tuned :).
