Owners of Carver Crimson 275 -Caution/Warning--Potential Increased Risk of Electric Shock

I have asked EJ Sarmento of Wyred4Sound the following questions on the ASR thread where he chimed in: 

"Folks have raised these salient questions to which there has been utterly no response--just conclusory statements by Malitz and now Bob. Maybe you could help answer them as your firm looks to have built a good number of copies.

1. Is mounting the DC restorer circuit by gluing it vertically to the chassis part of the design?

2. Is mounting the meter to the chassis by gluing it part of the design?

3. Are the Edcor 15w OPTs part of the design?

4. What gauge hookup wire is supposed to be running from the PCB to the speaker output terminals?

5. Does the design-manufacturing process allow for substitution of Panasonic film caps with Suntan brand or other lesser known caps?

6. Have there been reports of transformer hum? I have owned two units and both hum/buzz at the transformers with no signal and volume totally attenuated (not a sound coming from the speakers, but buzz/hum coming from the transformers (all 3)?

7. Frank Malitz stated there was a problem with transformers when the vendor deviated from specification, and that resolved. Would that vendor be Edcor? What can be done to silence the transformers for those with those issues?

8. Grounding. Are you aware of what many of us view as a problem with the grounding scheme in this amplifier? Specifically, several of us have the neutral running to fuse and no chassis grounding or ground to earth. Do you believe these scheme is safe and acceptable?

This unit is supposed to have a 5 year warranty and many of us are just trying to figure out where things stand.

I'm not trying to come at anybody. I like the amp. I'm just trying to navigate through this and Frank Malitz and Bob just say: (a) the amp is awesome; (b) the amp is totally safe: (c) everyone who hears it loves it; (d) Amir and associates test it incorrectly.

I'm sure you can appreciate that when a consumer spends $3k on something they want to know they bought what was sold to them and it is safe."

Carver Corporation Refund:

By the way, Bob Carver (by handle) chimed in on ASR offering a full refund to consumers who bought the amp if they want it, directing consumers to email info@bobcarvercorp.com

@jbhiller   So Bob offers a full refund to consumers of his product. This seems quite strange to me..as IF there is a safety hazard should he not be requiring all units in the field be recalled and corrected?? If there is no issue, why offer a refund? Plus, if there is a safety issue, why would he still want to have units in the field that could do harm ( maybe even kill?) and suffer the consequences of that action...doesn't really make any sense to me!

@daveyf , Agreed. Personally I like the sound of the amp quite a bit through high-efficiency speakers. However, this whole thing is a dog and pony show. I really respect Bob and what he has done for the hi-fi community. However, the responses from him and others associated with this, including Bob Carver and Wyred4Sound are just bizarre. 
 

I would be quicker to believe Bob Carver and his associates, saying that the amp is safe, if they actually gave a basis as to why. Specifically I mean, just tell me why from an engineering perspective this is safe. Instead they just make a blanket conclusion that it is safe and saying that you can have a full refund if you want it. They also do say that they will ground it to the chassis if you would like. That’s good. I was just looking for a little more transparency what is going on, especially from the folks that designed, manufactured and market of the unit.

With Bob getting older, it was time for him to focus on what he loved-- his family, his hobby, and designing audio gear. So I recruited EJ Sarmento of Wyred 4 Sound and we bought the rights to the brand keeping Bob as our chief designer-- effective January 2020 . I demoted myself (thankfully) from CEO to VP so I could no longer worry about logistics or paying the bills. Instead, I could focus on product development and building the dealer network as well as dealing with the public directly, something I love dearly. We closed our facilities in Washington state, moving everything to my office in the Chicago area and to our new factory in central California.

Unless I am reading the above quote wrong Bob Carver does not own Bob Carver Corporation. Bob Carver is hired on as a designer.

If a refund is being offered for the amp it is being paid by the present owners of the company.

FWIW, reading the first three paragraphs from the post of Frank Malitz on

AUDIOKARMA, Bob Carver was not involved in the production of the

Carver Crimson 275 Amplifier. That would probably included involvement in parts or parts quality.
