Welcome to CJO, great to have you with us!

Looks like an amazing system with some top notch CJ gear. I'm a big fan of Sonus Faber as they make some truly excellent speakers.

Again, welcome.

Looks like the AI bots are back. They have been hitting forum sites rather aggressively in the last few weeks. I have added extensive IP blocks and noticed that the guest user count has dropped by 95% so they seem to be working. Of course it's always a "cat and mouse game" but we should be doing ok ...

Just got back from a wonderful trip to Italy. Had a great time and we lucked out having ideal weather.

That was a great read. So much unique information that I was not aware of. Thanks for the link AJ!

Indeed, a big thank you.

Lots of fun to be had with this little unit. I plan to play around with it more.

Cool view. Definitely a unique angle. Glad to see it's really coming along.

The computer I am typing from is a windows7 machine, and I do not see where to upload photos from this computer.
Am guessing your computer is an older one, like mine.

As I have noted in previous posts, I use a ELP laser turntable. There are some unique advantages to utilizing such a device over a traditional stylus/cartridge setup found on most turntables. Notably, there is no wear on the record with playback. One can also adjust the area of the groove that the ...

I own the CJ ART amps. So I have 16 KT120's in there. I think they are absolutely wonderful tubes and there is good tube availability for purchase. I think the prices have even dropped to a certain degree since their peek. I think the Tong Sol made ones are by far the most popular but there are ...

Roberto had difficulty posting some pictures and videos and asked me to help put them on the site so people can see the progression of the house build.

If you are looking at new units. You can contact CJ directly and I'm sure they would provide any unit in any version for sale. If you have an authorized CJ dealer in the area, they may be able to help you out as well if you are looking for a specific unit version.

If the budget allows, then always try to go with the SE edition.

Nothing wrong with an MV75. The advantage is that it's going to be way way less expensive. It may give you more of a "tube sound" if that is what you are looking for. The downside is that you are buying a 45 year old unit. If that ...

It should work absolutely fine with the f208's. Those have a sensitivity of 88 db. Unless you plan to blast them at maximum volume you will not experience any clipping. Also, one of the positives with tube amps is that even if you reach clipping levels (which is very unlikely), it's a slow cut off ...

In that case, definitely take a look at the Classic 62. BTW, I think it will be plenty of power. It's quality vs quantity watts in my opinion.

Very exciting! I hope your health is being "built up" as quickly as the house! I'm sure it's very exciting to see it slowly take shape and getting closer to the finish date each day. Keep us up to date!

Hi Kevin,
Great to have you with us here at CJO.

Your have some great equipment but as you rightly recognized, CJ can offer a special sound that is rather unique and very musical.

With your current budget and looking specifically for new units you have the following options: The ET6 series, the ...

Not sure if this is helpful but there is a good high resolution picture of the board here: https://theartofsound.net/forum/showthr ... amp-SA-250

Perhaps you can look for the mod differences between your unit and the picture.

Unfortunately, we do not have the schematic in our database. If you do get a copy, you can send it to me and I will add it to our repository.

Use this calculator to give you the resistor values: https://www.digikey.com/en/resources/co ... color-code

I can't tell you by looking at the picture as the colors are always a little hard to tell with photos and I'm partially color blind!

Try to find a compatible solid state tube replacement. Should last "about forever". I wouldn't use bad tubes as they can cause voltage overloads and blow fuses.

Like this for example: https://amt-sales.com/other/tubes/12ax7ws-le/
