In Reply to: RE: Dunno about the solid state rectification. I loved the Cornet 2. posted by Opus 33 1/3 on August 23, 2014 at 15:36:16
Is the Mazda 5Y3GB a direct swap with the stock rectifier? No need to make adjustments?
thanks

No comparison.
Bought two from the link below to put in my Cornet 2 and Clarinet line stage but think they were the last two they had as they have been out ever since and that was 3-4 years ago.
Might try Fleabay.

Thanks for the heads up. I just bought one and it looks like he has five left. I finished my Cornet 2 about six months ago and this should give it a nice boost.
a big difference. Not so now. It transformed the Cornet 2 from a very good preamp to an excellent one. I think Perry agrees.

I've tried a number of other NOS tubes in that spot, but the Mazda keeps coming back.
I'm really looking forward to trying it out in mine. I was wondering if by any chance you measured the heater voltages before and after swapping in the Mazda?
Just for the record, I didn't see any change in heater voltage after swapping in the Mazda rectifier tube (6.05V before and after). I haven't noticed a world of difference yet with the new tube, but I've only listened to one record.
Is the 5Y3GB the same as the 5Y3GT?I have a Clarinet line stage and wonder if the Mazda 5Y3GB would be a improvement.
Yes that's the same transition, I'm trying. Did you build your Clarinet? I'm no expert, but based on the guys at the Hagerman site on AudioCircle, it's possible that the different tubes will affect the tube heater voltages differently, either moving them closer to or further away from where they should be. On the Cornet 2 the 12AX7's and 12AU7 I believe should be around 6.2V. If you have the time and know-how you may want to check these before and after making the switch.
until I read a report on Positive feedback and tried the Philips 5R4GYS myself in my power amp. Didn't make much of a change in my preamp.
they still can be had for about $65 @ Upscale Audio.
