My experience with hissers and buzzers was if it didn't burn off in one or two days it wasn't going to. Crazy thing is you still hate to toss them, so you just look at them and hate them
OK, another comparison for the 7LG delta3E4 Philips SQ E88CC / Valvo issue, '73s vs earlier/older:
Rolled in a pair of 7L4 *9K Amperex PQ 6922/E88CC (1959 D getter): These are little better when doing A/B comparison with the above '73s. In fact, they are amazing! But would I miss these if I started the session with the '73 SQ, definitely not. So, it would be amazing vs even more amazing. BTW This pair is a 1-2% match, both triodes and tubes with slight microphonics (tap only) in one triode.
Interesting to note that Philips/Amperex used the same version number 7L4 on both sides of the Atlantic. I always assumed they used different version codes.
Forgot to mention: IMO There are more similarities than differences with these two 6922/E88CCs from Herleen and Hicksville. I see more differences between the 6922 and the 7308.
How can you NOT bid on those... but go for the quad
Yer killin' me here. Yes, exactly true about the buzzing hissers. I'm practicing my Jedi powers on them. They. Will. Explode.
I was under the same impression about Heerlen vs. US change codes. Hamburg was definitely different.
I have the better quad on Watch. We shall see. My wife is giving me the stinky eye.
