Need to recap my Classe Audio DR-8 Amps - need suggestions


I recently purchased two Classe Audio DR-8 amps. The amps were barely used and are in mint condition, but I think I need to have them recapped due to being over 20 years old. I am guessing Classe Audio would be the best place to have the amps recapped, but I am not sure. Any suggestions where to have the amps recapped and what I should expect to pay?

Also should I recap my DR-5 pre amp?

Thanks.

Jon Soderberg of Vintage Amp Repair.   He was a part of Threshold back in the day.   Once in awhile something comes up for sale that has been refurbed by him.   Lot of good reports as to his work.  Ive never had him do anything for me but have communicated a number of times and would definitely go with him considering the wealth of experience he has and is located in Cali.

I had my DR-8 recently serviced by Paul at EBC Electronics in Mansville NJ. I paid $550 including all parts and labor & NJ Tax. Made a huge difference in the overall sound and presentation. Any good electronics technician should be able to that.
