Hi,
Found this old thread (CineMag CMLI 15/15b ) over in "Group Buys" and asked the following:
Was wondering how everyone who purchased the CineMag CMLI 15/15B input trannies liked them? I have a ground loop problem that I temporarily solved by lifting the power ground. I have read online where using an input transformer would also solve my ground loop problem. I emailed CineMag and they suggested using the CMLI15/15B. Which brings me here and with a question or two:
First, when using these transformers, is there any affect on the sound? Any lose of frequency extremes?
Second, my tube amps use the JELabs 300b circuit with a 100k input load. Is there anyone using these trannies with a similar 100k load and a preamp? My preamp is an Accuphase C200 model and seems to mate well with my amps.
Finally, these trannies look to be well shielded. Will it be ok to mount these inside my amp chassis, as long as a take care to keep them away from AC sources?
Any help with these questions would be most appreciated.
Regards,
Danny

I have some of that model Cinemag, as well as the 10K:600 model. No problems with frequency response, any reduction in brightness or sharpness at the top end is due to removal of noise rather than signal. Benefits outweigh any perceivable disadvantage. Yep ok to mount them inside the amp - best to keep the secondary wiring as short as possible. Worth playing around with the loading - 100K works well but is not the sweet spot. I ended up with about 22K but who knows.
Cheers,
Mike
