Re: Premier 16ls Transformer Replacement
Good investigation work. I'm not surprised that the same transformer is being used in multiple units. If you find something you like, you stick with it. Also makes stocking extra components easier as your total parts list is smaller.

Re: PV-12 help needed
If you think the resistors are not functioning properly, really the only way is to pull them and measure their resistance. My general rule is that if I see any visual abnormality (whether be it resistor, cap, etc...) such as burn marks, deformation, discoloration, I tend to replace them. These kids ...

Re: Cannot find member details
Glad it seems to be working ok. VPN can sometimes do funny things in my experience (although really good for security, especially when using public wifi). Later this year I plan to move the site to a new hosting provider as I am not very satisfied with the current one we have had for 10+ years. This...

Re: Cannot find member details
Can you try again, maybe with a different browser? It works for me, and I also tried it with your user permissions as well.
Perhaps someone else could confirm as well?

Re: MV-55 - most significant improvement yet
Thanks for the writeup. I may do an upgrade on my MV-55 in the future and there are definitely some great ideas here.

Re: CJ ACT2 hex bolts
Welcome to CJO. Great to have you with us. I'm sorry I don't have an answer for you but if you don't hear back I would recommend getting a thread checker. They are under $20 and you can check on the size yourself. Probably a nice thing to have in the tool box anyway. Something like this for example:...

Re: MV-55 anyone with experience of this?
Sounds like these upgrades will keep the MV-55 running flawlessly for many years to come.
May I ask how much all the replacement parts cost? As a fellow MV-55 owner, this is something I may consider doing in the future.

Re: Oh! For the love of tubes!
But all the others are at the mercy of unfriendly, fickle sources. And this is my biggest concern. I don't think their can be relatively inexpensive quality tube production in the West. Russian sources are shut down for all intents and purposes. And we have not seen quality tubes coming out of Asia...

Re: CJ HQ Audition System Upgrade
I'm in a similar boat. Last time I heard Zellaton speakers was a number of years ago but I was very impressed. It was outside of my price range so it was more of a "fun listen" vs true consideration. I think if CJ is dropping big money (for a small company like them) on their listening roo...

Re: Oh! For the love of tubes!
Burmester makes some incredible gear. Not sure how much "better" you can get in the SS world. Maybe, something like Dartzeel, but now the price is going through the roof.
RJ, I think you are a tube guy like the rest of us. Why try to find SS options when it's the tube sound you like?

Re: WARNING: incorrectly labelled, but EXPENSIVE, V-Cap and Solen PTFE capacitors
It's odd that Solen would not view this is a problem to the extent of properly (if at all) marking their caps.

Re: WARNING: incorrectly labelled, but EXPENSIVE, V-Cap and Solen PTFE capacitors
In all honesty, I think your supplier is making claims that are not supported. The data sheet from Solen is going to be the final word. I've only bought Solen from Solen directly so can't speak about 3rd party suppliers.

Re: WARNING: incorrectly labelled, but EXPENSIVE, V-Cap and Solen PTFE capacitors
Do solen caps even have markings for polarity? I'm trying to remember if I saw anything on the caps themselves to indicate direction and I just don't remember seeing anything on them. Maybe I'm just forgetting?

Re: WARNING: incorrectly labelled, but EXPENSIVE, V-Cap and Solen PTFE capacitors
Interesting videos. Question, is the noise only introduced if there is something coming into physical contact with the backwards cap?

Re: WARNING: incorrectly labelled, but EXPENSIVE, V-Cap and Solen PTFE capacitors
I'm familiar with how a capacitor functions. I don't recall this information on the solen caps I have bought before (similar to the black solen cap you have in the picture). Makes me wonder if I installed them correctly (last time was a cap replacement in the crossover for my magnepan n 20.1 speaker...

Re: McIntosh C-22 MKV In The House
It's a little beyond "a 3 year old", but the basics are pretty easy, and it can do a lot if in the future you really want to get crazy with it.

Re: McIntosh C-22 MKV In The House
Interesting little device. I use active room correction/equalization in my home theater setup. It's near impossible to calibrate 8+ speakers all at once with simply "moving them around" or putting acoustic treatments here and there. However, my expectations of hometheater is very different...
