    MY PSvanne is in, warming it up with some TV atm, will chime in with specifics in a couple of days

    Hi @Mshenay, good to hear you've got them, I'm torn between the Shuguangs and the Psvane, so will be interested to hear what you think of them, one more thing would you mind if I ask who you purchased them from?.
     
  4. Mshenay Contributor
    eBay there's an official re-seller there and I don't have a Shugang sadly, just the Psvane

    Hi, @Mshenay. How are you getting on with the PSvane's, have you come to any conclusions as to how they sound?.

    The hifiman ef100 is designed around the 2C51, also known as 6N3J, 6N3P, 396A and 5670, which is a miniature 9-pin all-glass tube. While it might be possible to use the 6SN7, it would definitely require a pin-adapter. And further, there might not be enough room for the larger 6SN7 to fit without modifications.

    Possible upgrades to the stock 6N3J include Sylvania and Bendix.

    can i ask would sylvania and bendix need and adaptor or would they fit as is

    and what sound differences if any to stock would I expect

    First of all, the Sylvania and Bendix versions of the 6N3J do not need adapters. They are plug and play. Since these tubes were marketed under several different tube numbers I find it most useful to search separately for each number. For example, go to eBay and do several searches: "396A tube", "5670 tube", "2c51 tube". You will see Sylvania, Bendix and other brands.

    My current amp uses 6SN7. In a previous amp I used to roll 2C51 tubes, but that was quite some time ago and I no longer remember much about their sound. I do remember that I favored the Sylvania and Bendix, but again, can't remember why....

    Garage1217 makes some very nice amps and a few very high quality tube adapters as well.

    One pin-converts so an 8-pin 6SN7 can be installed in place of the 9-pin 12AX7 and its many related tubes.

    Another pin-converts so an 8-pin 6SN7 can be installed in place of the 9-pin 5670 / 2C51 / 396a and related tubes

    NOTE: Check for compatablity with your amp manufacturer before using different tubes. While adapters make them fit, they do not change the electrical properties of a tube.

    There was recent chatter in one of the threads around here about the Tung Sol 6sn7 GT Mouse Ears, so I thought I'd try one. I'm using a Project Ember ll and have two Sylvania 6sn7 GTB's, a Ken-Rad 6sn7 GT, and another Sylvania 6sn7 GT to compare to. One of the Sylvania GTB's is a standout and my favorite.

    I found one on eBay that said 'New Listing' , whatever that means. It was reasonable so I grabbed it. It appears to have been a good decision. Comparing to my best Sylvania, it is cleaner sounding with better upper detail which gives the sensation of more air. Better midrange, vocals. The bass is not as strong but tighter. But that is easily remedied with the Schiit Loki. It also has a silent noise floor unlike the Sylvania that has slight noise on the left channel.

    The tube of course was listed as a Tung Sol but there is nothing on it that I can detect what, exactly it is. I'm thinking maybe that the tube was funky and the vendor might have cleaned it up, removing any markings. Does that sound plausible? The other thing is that it has a brown base. (It might be a little hard to tell in the pic) I can't find any information on brown base Tong Sol 6sn7 GT Mouse Ears.

    Is there a way to tell exactly what this is for sure?

    Edit to add: It's a very dark brown on the base. Maybe that's not considered brown?

    Decide to take the plunge and have my biggest ever spend on tubes for a pair of Psvanes CV 181-T MKII, always a gamble as to whether you'll like them or not, this is a bigger gamble than most though! s-l1600.jpg,.jpg
