In the CLSIIZ, there's not so many parts to change so I will surely try it. Building something point to point wiring 'on the air' would be simple and fast. If it is better, as stated, I'll use a teflon board to do it permanently. This is not for having an easier load for the amp. It is just a...
Thanks for your reply
Yes I thought upgrading caps and resistors . I'm not a fan of Solen caps and there's many in the crossover.
Before doing Mods I would really like to have someone who has done the CLSII mod to IIA tell me if the IIA is really better.
As for the bass, I use a Descent I sub...
Hello
I have all the instructions to do this task but before doing it I want to know if someone has done this mod.
In fact, about sound, is it really better . What will I hear different from CLS!! to CLSIIA mod ?
I could ask the same question from CLSIIA to CLSIIZ crossover but I read that the...
As my amp has an input capacitor, I could just use a higher value and adjust it to get 60 hz high pass filter. This would be 6 db/oct slope. I suspect they don't use top quality caps in the Parts Express in line crossover. By it's small size, it will probably have an electrolytic capacitor.
I am wondering if someone tried to bi amp CLSII
This should be easy to do by separating the inputs + and - of the two transformers and feeding each with a different amplifier.
Thanks.
I finally used an 'old' Classe DR15 which was recapped with my CLSII. These amps are indestructible and superbly well made. My Melos Single ended 75W mono blocks can drive the CLSII but treble is lacking. The mids are glorious. I will probably adjust the caps paralleled on the negative feedback...
10 years ago, I also had horns. An Onken with Altec 1005B and a JBL2405. All was triamplified with single ended triodes. I loved the easy efficiency but this system was 'fast' and (too) intransigent with music. if the recordings were not the best, you knew it fast and you had to listen another...
Today was the day to try the setup. After fiddling with the placement, I finally placed them in the room with the calculations ML recommend. After, I adjusted the Descent I sub cut off frequency and phase with pink noise + analyser. The Descent I goes to 80 hz with the CLSII in my room...
Here are picts of the CLS I have to place in my listening room. They have to dethrone my 3A Reference 2002 which were the best combination of planar and cone speakers. I loved them. Also a pict of my system. More on that after 24 hours of powering the CLS in the 120V
Yes, I got them last week
I repaired the frame of one speaker which had an open wood joint and I installed them in the wood frame I had with them. They're powered in the 120 V since 8h00 yesterday. I will position them today and I will probably do my first listening tonight.
One of the biggest problem with these amps is bad contacts with output tube sockets. If you ever buy 6P45S, carefully clean the pins. These tubes are NOS (new old stock) and pins are often badly corroded,
Output tubes for the Melos are still easy to find if you buy Russian 6P45S military tubes. There are Ukrenian sellers on eBay. I can attest Svetlana, OTK sounds good and are rugged tubes. Ham radio peoples still use 6KG6/EL519/EL509/6P45S so that's why they could be hard to find someday.
After many hours (or days) working on these beasts, they never broke. I bought a 6P45S batch to be sure I could be safe for years. Presently, I drive speakers which have 91 db/1W/1M with them. I always have a really low residual hum. Did you have this problem ? If you ever see parts for these...
