Ok so there hundreds of different tubes out there. Some sound great others, not so much. Mullard and Telefunken are getting rare and pricey. What signal, power and rectifier tubes can you say are good with a good price? Some new tubes such as Gold Lion are said to be very good, as are the new Mullard and Tung-Sol tubes. There are many NOS tubes as well that can be had at for a good price and excellent sound. What has every one come across that they can recommend as a decent tube at a decent price? And no, the 3--B tubes on Tube Depot site at $19,900 a pair really are not a bargain!
