Step Up Transformer Question
@mulveling it's funny, that's what I was initially thinking. I messaged Ned Clayton about an SUT that would have some adjustability so I can play with different gan ratios and then I can adjust my tubes in my phono pre accordingly. I'll probably e... 
What to do with a large collection
Our local friends of the library group does book sales where they also sell CDs. There are often many classical CDs. You won't get any return on your investment but it will do a great deal of good for the local library.   
Step Up Transformer Question
@mulveling I appreciate your input. I spoke with Roger at Roger's High Fidelity who makesy phono stage and he said that the 20db I'd get with 1:10 will get me a total of 70db of gain which is what I'm currently using with the built in SUT. It seem... 
Step Up Transformer Question
@rrc4860 thanks for that input. I was looking at the MCX which is 1:10 and a bit more expensive. Thinking there just be a higher quality transformer inside? I'll call the guy at Britaudio next week.      ​  
Best Options For A Tubed Preamp - $2500 Or Less, Preferably Used To Maximize Value
If you want certain sound qualities it's important to pay attention to what the tubes in the unit are. I tried a few 12au7 based preamps and was never satisfied noatter how much rolling I did. When I switched over to a don sachs model 2 that used ... 
Step Up Transformer Question
@atmasphere Ralph, thanks so much for your input. Yes, the plan is to use the MM input and which has about 45-50db of gain with the current tube complement. I should really only need about another 20db which, if I understand correctly, would be a ... 
Step Up Transformer Question
@pindac I see now on the Erhard audio page the area that lists nano crystalline transformers but I don't see any that are marked as SUTs. Will have to give them a call  
Step Up Transformer Question
@pindac I'm chatting with an eBay builder about building one with lundahl 1941s. The core is listed as amorphous. Is that what you're talking about?   
Step Up Transformer Question
@elliottbnewcombjr the Bellari SUT I have now to play with has 1:30 as well and when I switch to that the hum does not go away. I really think it's cable related but can't prove that until I get more cables.  @pindac you did mention the sculpture... 
Step Up Transformer Question
@elliottbnewcombjr you got it. The total gain with the inbuilt SUT and 12ax7s in P place is 70db. My understanding is that if I place a 1:10 SUT on the MM input it will have the same. @lewm I appreciate what you're saying and in truth, yes, I ag... 
Step Up Transformer Question
@tomic601 you are correct sir. My wife is an absolute saint. She mostlybsupoorts my hobby and doesn't ask too many questions. She even used the turntable sometimes! @elliottbnewcombjr was that TT set up with a SUT? I'm definitely getting more hum... 
Step Up Transformer Question
Might as well ask this audience... What phono cables are you using? I don't want to go crazy. Found some on eBay that look fair, low capacitance with good shielding.   
Step Up Transformer Question
Thanks for all the input. @lewm I know subbing 12au7 for 12ax7 seems off but the amp is designed to take 12au7, 12av7, or 12ax7. Each has increasing gain but also increasing noise so if I can get more gain out of the transformer then maybe I can ... 
Step Up Transformer Question
@theflattire this is super useful information. As I said, I'm using some crappy found interconnects to go from the SUT to the phono. I have some better shielded low capacitance cables coming soon. Maybe those will solve the hum problem. Seems like... 
Manley Chinook SE MK2
I have a Rogers High Fidelity PA-2 and I've not heard anything better. It has an interesting feature where depending on the tube you use, it can provide different levels of gain. I'm currently running an Ortofon Winfeld Ti and it's output is only ...
