You need to use more heat on your soldering iron

BTW guys, I decided to "go all out" and get the NOVIB Socket Saver© due to how tight the socket is with NOS tubes.


That's what I posted about (and lost it) definitely worth it. Chance of breaking the original ? Slim...but if it does, what a pain in the ....
 
My caps, black and gold...but

lol I gotcha, I would have understood if you said pins!

Well yea you can find the cheap Chinese ones all over Ebay, but if you want quality ones with silicon dampening and the female pins modeled after NOS Philips pins (and the pins are gold/thicker).
 
Nobody is saying you have to buy these, it's just those with the funds available are going for them.

Yea I'm not a fan of the LED under the stock socket, reminds me of guitar effects pedals that don't really use the tube at all.

I think most people hate it. The white color blocks any glow from the tube. CoiL put a red disc of some type over the LED which looked much better and gave an illusion of tube glow. With the socket saver the LED will be blocked but the tube will have very little glow because it is being used as a buffer only. Ironically even the Woo WA7 uses an LED under the tubes, but at least it is red.

Very cool...congrats..I have to figure out what to do with my overload of tubes...LOL

Interesting AUNE Capacitor find..
 
So I finally got a capacitance tester today and decided to do some reseach
 
tested the 330Uf caps from Panasonic - 350 reading
 
Tested the Elna 330uf - 341 reading
 
Tested the original purple caps - 335
 
so they are spot on..Now..that could be because these are broken in vs the other two which have never been mounted....but the point is..they aint that bad...

You can't judge a capacitor simply by the farad reading and there are multiple ways it will vary, the main one being heat and age.
 
You also have to "worry" about ESR of a capacitor.
 
This is a great guide and general information on capacitors that I have used in the past: http://www.repairfaq.org/sam/captest.htm#ctcoo
 
I doubt there is anyone in here that won't learn something about capacitors and capacitor testing from reading that web page.  I am an Electrical Engineering student (Jr.) at North Carolina State University and I learned many things from reading it, so check it out if you want to know more about caps and cap testing.  You can technically test a cap with a normal multimeter, but you don't get as much info as you do with a Capacitance Meter.

Very true on the ESR....Thanks for the link ! I just fixed a vintage Yamaha M-65 power amp today...I had recapped it and it had a slight imbalance. Turns out that setting the idle voltage (10mv) need to be done after it warms up MORE than the 2 minutes the service guide recommends...Now all my amps are set and I can switch between Tubes or Solid State

Yes, I looked at those also...but I have come to learn sometimes in some things...the money is worth it...and trust me, I am frugal..I go by quality for price ..not just price ...hey they will work for him though.. all that counts..

I checked my caps with an ESR meter.......
