Supratek Tubes and Tube Swappin' for Everybody

Has anyone tried the new Tung-sol "Reissue" tubes. I have just installed their new 6L6G big bottles along with a pair of brand new nos GE 6SN7GTBs in my Chardonnay and it is a match made in heaven. I am using a Mullard GZ33 in the power supply but like to try a Bendix 6101. If any of you guys have a spare one that you would like to sell then please let me know.

Syrah/Chenin tubes

I have a Syrah which is the same as the new Chenin (or Chardonnay plus phono). Most of the discussion here is about the Grange or Cortese or higher end models. So I'm not sure what applies to my Syrah. I'm currently using the following tubes from tube depot:

Regulators: Sovtek KT66 $49.95/pair
Line Stage: EH 6SN7 $11.95/pair + $2 to match
Rectifier: Bendix 6106 $39.95 ea

Are there better options for the Syrah? Can I even use the TJ 300B, TJ PX/4 or Sohpia 45 discussed here? Or does my unit not support the correct volates, etc? Other options I should look at?

I'm a big clueless here.

Thanks in advance!

Netexpress,

300B, PX/4 or 45 tubes are designated for various incarnations the Cabernet and Grange. These tubes are not to be used with the Syrah. Your instruction manual that was supplied with your syrah will outline the tubes that will work with the Syrah.

What is your budget for retubing?

6f6gt works quite well in the regulator position. NOS tube rolling in the line stage has been described this thread.

Hello,

First off, let's make sure we are only talking about the Syrah here.

You cannot use the 300B, PX4 or 45 tube replacing the 6SN7 tubes or any other tubes in the preamp without any modifications. The most obvious reason is that 300B and 45 have a different pin configuration, and number of pins, thus, different sockets required. The DHT (directly heated tubes) 300B, PX4 and 45 requires 4 pin sockets usually called UX4 sockets while the 6SN7 requires an octal socket (8 pins).

Let's leave the circuit characteristics of the Syrah for now.

regards,

Abe

Thanks for the clarification about which tubes may be used with the Syrah/Chenin. That's very helpful! I'm a tube novice :)

Powers - price isn't so much of a concern. I can spend as much as might be suggested if it will result in a corresponding increase in sonic results. I guess I'd put a cap on price only to the extent that the tube prices recommended are so expensive for my little Syrah but the resulting improvement is so small due to limitations of the Syrah that one could barely hear it than it might not be worth it. In that case maybe it would be worth looking at jumping up from the Syrah/Chenin to a higher end model preamp like a Grange or Cortese instead that can really take advantage of a better selection of tubes. Does that make sense? I guess it comes down to bang for the buck and living within the limitations of what can be reasonably expected out of a Syrah.

I was attracted to this preamp because of the extreme value it offers - best bang for the buck out there according to many and I haven't been disappointed in the least with its performance. But I lack knowledge in the whole world of tube selection so I'm a bit over my head in this department. If you have any suggestions that would really improve the sound of the Syrah I'll give it a shot. but if you think I may already be near it's limits and probably shouldn't toss too much into more expensive tubes for this model because it would be a better bang for the buck to upgrade the whole preamp I would take a look at that too. But honestly I'm pretty happy with what it has brought to my system so far. It is a huge improvement to the SS preamp I had before without any doubt. Right now its paired with a Pass Labs 250.5 and some older Watt Puppies. The tubes I have currently are the following from tube depot:

Regulators: Sovtek KT66 $49.95/pair
Line Stage: EH 6SN7 $11.95/pair
Rectifier: Bendix 6106 $39.95 ea

Thanks in advance for your help!
