I am selling my upgraded Jolida 502A 60W/ch integrated amplifier which is in mint condition (see ad pictures). Sale price is $850 OBO + shipping.
The 502A has the much in-demand classic tube amplifier look where the transformers are not covered.
The reason for the sale is that this amp cannot drive my 1-Ohm speaker load.

My Jolida 502A has been significantly upgraded by K & K Audio for a major improvement in sonics. See ad picture of amp guts showing modifications.
The modifications are:
* all power supply caps were upgraded to computer grade Panasonic TS-HB.
* AC power rectifier diodes were upgraded to IXYS FRED diodes rated at 1200V, 52A.
* All low current rectifiers were upgraded to 1000V, 1A type.
* All signal path caps were upgraded to Kimber Kaps.
* Transistor Current Sources were installed for the 12AT7 driver tubes (this was a big deal upgrade. Resulted in major sonic improvement).
* The Volume pot was upgraded to a NOBLE logarithmic pot.
* The Balance pot was removed altogether (this was a major upgrade in sonics because an uneccessary pot in the signal path was removed).
* All resistors were upgraded to Holco or Kiwame or PRPor Caddock depending on location.
* Input stage tube upgraded to Mullard IEC 12AX7
* Driver stage tube upgraded to RCA 12AT7
* Output tubes upgraded to KT88EH.

If you want to buy a brand new stock 502B it is going to cost you $995 from Underwoodwally on Audiogon.
If you want to buy a modified 502B from Underwoodwally it will cost you $1595.00
If you want to buy a 502A with Platinum mods by Response Audio it would have cost you $2125.00.
I think that my selling price is very fair.

The tubes that come with this amp are
Mullard IEC 12AX7 (in generic white boxes) ?³ used old stock.
RCA 12AT7 (in original RCA boxes) ?³ used old stock
Electro-Harmonix KT88 (in original boxes) ?³ I have about 50 hrs on these tubes. They are pracitically brand new.

On the rear panel there is some fading of the numbers indicating the 8 & 4 Ohms taps. It is still very easy to make out which is the 8 Ohm tap & which the 4 Ohm tap. Just the numbers 8 & 4 are somewhat faded.

I have the 502A manual + the electrical schematic that Jolida sent me to help out with the mods. I have the original 502A shipping box.

Payment is preferred via PAYPAL using your checking account.
Payment can also be by cash.
NO CASHIER¡¦S CHEQUES. NO EXCEPTIONS!

If you live in Greensboro/High Point/Winston-Salem, NC you are welcome to pick up the unit.
Unless otherwise requested by the buyer, I will ship FedEx Ground within the continguous USA.
Buyer pays all shipping + insurance costs. The shipping weight is 50lbs.
Email me your zip code to calculate INTERNATIONAL shipping + insurance costs. INTERNATIONAL BUYER IS RESPONSIBLE FOR CLEARING CUSTOMS.

Thanks for looking @ my ad.

Nice price.  Too bad I already have a modded 302A, otherwise I would jump at this unit.  I think you picked the best 12AX7 and 12AT7 types for the amp.  I have tried many 12AT7s in my Jolida, and have settled for RCA black plates.  I also use NOS Mullard 12AX7 or Sylvania or GE 5751, depending on my mood.

Thanx ltr317 for the approval of my choice of small signal tubes. 
You know of anyone who might want to buy an upgraded 502A?

Not offhand, but I'm attending a couple of audio club meetings this week and will ask.

Hello ltr317,
During your audio meets last week did you get a chance to ask any of the other audiophiles if they would be interested in my upgraded Jolida 502A?? Thanks.

Yes, I did.  Unfortunately no takers right now.  How about posting on some of the other audio forums, like Audio Asylum and AudioKarma?

Thanks much for asking around, ltr317.
I have posted my ad on Audioasylum & my local Craigslist.
I did not think about Audiokarma - good idea, thanks!

added a pix in the ad of the unit for sale - save the potential buyer from needing to view the Craigslist ad.
I had taken the tubes out when I took a pix - hope that this does not matter to the potetial buyers!
