I have a Jan Phillips 5751 tube that I tried in a Peavey Classic 30 for about an hour.
Includes box. I don't have or use PayPal, so this is a Money Order deal.
Please check the details in my feedback for Money Order deals.
This tube has the Low Noise and Microphonics upgrade ($4.00).
These tubes sell for $38.95 with upgrade + shipping.
I'm asking $25 shipped with care. It will go out USPS with Tracking.
If you want to reduce the gain of your amp so you can reach that creamy tone without blowing the windows out, then this is THE tube to get. Fully interchangeable with a 12AX7 tube, the US made JAN Philips 5751 will allow you to drive the power stage harder with less volume. Compared to the Sovtek 5751, the JAN Philips 5751 has a smoother response that is the ideal way to get the tone you are looking for.
Here is the link from Tube Depot, where I got it, for more info: http://tubedepot.com/nos-5751jan.html
