Hey guys, Jeff Rowland has a friend, Ron that deals in his older equipment. I purchased my 6's and BPS from Ron and was referred to him by Jeff himself. Shoot him an email and let him know you are looking for batteries and he may stumble across a source from them. He is a very good guy and knows Jeff's equipment really well. Here is the email to reach him, I believe:firstname.lastname@example.org.
Good luck; the batteries are awesome; lower noise floor, smooth sound, very musical.
I just saw your other threads from some time ago. Interesting that you also have dipoles, and even ones that require even more power.
If you can get the batteries, by all means do so! The sound field opens up and it is even closer to tubes, yet, with greater realism.
If it is of interest, I have used the REL sub along with my Quads, and it is very well intergrated. It was amazing to see what the 6's brought out in the lower end of the spectrum with the REL.
Do you have any info on how A class our 6's are? Is it for the first 10 watts or so?
This is interesting. I spoke to Jeff and it is possible that one may run hotter than the other depending on what each speaker is drawing in power.
However, in my set one of the amps is running cooler on one side only.
So when I get back after new years, I will recheck if the fuses have been blown again on the temperature control system.
According to Jeff it is possible that since there are seperate amps left and right of each unit, only the temperature elements may have trouble, if the sound is equivalent on both amp units.
Will get back to you in a week or so.
I have these amps without the bps and they drive Soundlab m2's and usher rw 723 monitors and one channel seems to run hotter than the other and never thought it was a concern as class A amps run hot (hotter) than other class amps.
I would call rolands tech support group to get their opinion as well.
My battery question was to see if the amp section acts the same without the batteries being used.
