if the tube broke when inserting should the amp work? I played the amp for a while and the tube worked.The valve has gone to air due to the incorrect positioning of the pins and a forced insertion.
Not a fault of the valve.
Glass cannot bend and the misplaced pin broke the seal.
It doesn't matter if the valve cost £0.30p or a ridiculously high priced £135, all glass will break when abused.
so unless the vacuum takes considerable time to fail after breaking the glass, i think it was not the case, i played the amp for some good time and it worked normally. For sure the pins bented while trying to remove the tube once i noticed it was dead since it was made almost in two parts, but while inserting i always do it gently and with deliberated care so that i cant be 100% sure it was not due to bad handling, but i think it is improbableAs the vacuum fails, the valve will lose functionality.
Yes, here is one I thought you might find interesting.Never look at the printed logo. Look at the etched code. The triangle means Heerlen NL, B means Blackburn UK. I have Blackburn logo tubes made by Telefunken...
I have 3 of those Hamburg long plates with philips label. mC1 and mC5 if I'm not mistaken. And also I60 short plates from HamburgYes, here is one I thought you might find interesting.
Mullard black logo, BUT it was really made in Hamburg (1956). The code is D6.
The Hamburg ones are really, really outstanding.
Air enters the valve slowly in the case of a crack in the glass when it is on the base.if the tube broke when inserting should the amp work? I played the amp for a while and the tube worked.
Yep those are not original Mullard 50 year old boxes. Fonts and printing all wrong for that period too.I will admit, the cartons are a nice touch, but really, who's going to believe 50 year old Mullard cartons in absolutely pristine, unfaded condition, either? That's just as suspicious as the misspelled stamp.
Sometimes, you can get lucky.......Yep those are not original Mullard 50 year old boxes. Fonts and printing all wrong for that period too.
