Audio Research Reference 3 Seeking help


Dear Brothers,

I am Michael from Hong Kong. I bought my Audio Research Reference 3 Preamp from the previous authorized Hong Kong dealer in 2008. Now I intended to upgrade the said 4 pcs 0.0024 coupling caps inside the Ref3 but the present authorized Hong Kong dealer refused to help me to make such order.

Would you guys offer me assistance to that? Of course, I must pay you back the charges in advance, if any.

Thanks for your help.

As told above , the 4 bypass caps are an official revision
by ACR NOT a modding .Michael I think the easy way is buy the 4 caps , ARC used infinicap with a voltage of 400V.
Let these 4 caps installed by a technician , it is very easy , the are parallel at the backside of the 4 big goldcolour outputcaps of 10 mF.You don 't have to dismantle
the unit , space enough.The caps are easy ordered at any
retailer of electronic parts.Remember , they are installed
in every ARC unit standard now ( EQ CD 7 )
Techalliedsinatown,

Why do you have to buy from Hong Kong dealer?? Google for ARC dealers in other countries and have them order for you. I'm VERY familiar with HK and easy to find a qualify tech to install them if you can't solder.

Another avenue is investigate using different brand caps but same values. Parts Connexion (PCX) has a HOURLY overstock sale so you can get some good deals.

My consultant bill is in the mail ...

Good Luck!
ARC never used .0024mfd as a coupling cap. I do not know where you are getting your info from. That value is way too small for a coupling cap as well as for a bypass cap.
I would complain to ARC about this dealer, who would want to buy anything from such a person unwilling to help with a product he represents?
Hello Hifigeek1,
Could you please tell us the value of this bypass cap ?
Some time ago the ARC importer give me the new 6550 tube , but said to me the 4 bypass caps would not give me a better sound .In my schematics the 4 caps are of course not mentioned . They are listed however in the CD7 and installed in the factory.In this schematics ( SEP 26 05 )
C5,6 are listed as 0,0024mF 500V INFINICAP.Did not verify in my CD7
