Are you in the US?

I am in the Netherlands. And i also got hold of a 2x i think and some 3s without the woofers. They are next on the recap list.

they must be in parallel (not series as you wrote in your first post).

Noted, thought parallel wrote series.

I dont have any questions about the capacitors , i am a natural worrier so when capacitors are supposed to be 68 and measure 75 i need to double triple check.

I got this new peak ESR70 meter for just capacitors I'm relatively new with this electric stuff.

But i also read in some of your posts that its all ok, i mean the difference is in the 5% noted on the capacitor.

What exactly did your friend provide?

 

This is what he made for me.

Hi thanks for the welcome. The answers i meant were also about which capacitors to use. I saw a distinct pattern 😂 .

Is there any sonic difference between the L-pads and your offering ? Your shipping from the states ? How long would that take to europe ?

Already bought the L-pads but luckily i have more AR speakers that also need restoring. I went on a collectors binge 10 years ago, need to get the whole series complete AR1 through AR10.

I read on the forums that the 5 deserves the most love because it is designed the best ?

Of course now i am reluctant to use the Mundorfs. I'll get them tested again by a friend just to be sure.

Thank you.

Hi I am finally restoring my AR-5's and in the process of finding the correct way to replace the pots for L-pads found all the repeated numerous answers going back to 2005. Thank you @JKent.

Downloaded the 3A manual looked intensively at page 15 etc.

2 questions remain to make myself at ease, because i found the answer but first time doing this so want to be absolutely sure .

The 25 ohm resistor is placed across 1 and 2 terminals of the l-pad, which are connected to the driver terminals. It is the variable parallel leg of the l-pad (corresponding to 2 and B of the original control).

This goes for all AR models ? Because i finally found that sentence in a 3A post.

I got some nice NOS capacitors from a tube friend to use with the 4uF and 24uF but for the larger 72uF i bought 2 68uF mundorf ecaps that measure 75uf.

Is that ok to just use or should i stick to the label and add 4uF in series to get the label values right ?

Kind regards Oliver.
