Read the manual. It says 'if you replace a tube you need to send it to Audio Research to have a technician adjust it'. In other words.... we want $530 to replace your power tubes.

They should give these away, they'll make it all up in service fees. It's astonishing to me that in 2022 a company makes a five thousand dollar amp that the user can't set the bias on. What are they thinking? They're thinking 'hey, we can charge $510 to replace the power tubes in this amp'.

I have a two thousand dollar Black Ice F22 EL-34 that is dead quiet, sounds great, only cost two grand and I can bias the tubes myself in under a minute.
Most manufacturers of ARC caliber would prefer you use their service stations to tune or service their products. I think it’s normal and a matter of pride in their designs. The I50 is not self biasing as many of the ARC products are. This is also understandable when a company is trying to meet a price point.

While I don't think this is the case in america, it could generally be for legal reasons.

For instance I am in germany and not allowed to use my tube amp without the cage for safety reasons, according to manual.
Or if a fuse blows, I need to send it to a "qualified technician" in order to exchange it.

While we all agree that this is stupid, the manufacturers have to do it, or could be Held accountable for any injuries occuring from improper use while changing tubes/fuse/bias whatever

Don't know about Germany, but if you're talking about the U.S. you are just flat out 100% wrong.

American tube amp companies are not required to have people send their amps in for biasing. 45 years ago Conrad Johnson had a little LED on the top of their amp that you could use to set the bias.

If Germans can't change a fuse... that's just crazy.

Just like Germany the US tube amp manufacturers must provide a tube cage and the consumer is asked to use it. We have no laws that a fuse be replaced by the manufacturer or service station but it is and always has been recommended. Our safety standards in the USA are simply that a standard of practice but not always required. I personally don’t think he’s crazy. He’s simply telling you the standards in Germany and he stipulated he was referring to Germany at the onset. CJ is one of the darkest sounding tube amps ever made. Not much biasing can help that aspect of their products.

The other aspect of this is, you should never leave your tube amps running while your not there to monitor it. This is common sense to me, but I have run into a lot of people that have no clue about this. You never know when one of your tubes will cross filaments or just outright blow. If your not there you could be in for a rude awakening when you get home; To the tune of your local fire department hosing your house down to put out the fire.

Approximately when can we expect to have a few more details on this interesting P50 headphone/pré-amp?
