tuner upgrade expertise needed


Don Scott informs me that he is no longer modding tuners (much to my dismay).
So I am seeking referrals for repair + upgrade of a 4 year old Magnum Dynalab MD102 solid-state tuner.
Don Scott’s mod’s include:
power supply, audio output IC and caps, better IF filters, modification of the blend circuit

A forum archive search has found:
referral to TRL (what is TRL and how do I contact?).
referral to Joseph Chow.
referrals on FMtunerinfo.com website to:
Audio Video Service Labs
Bill Ammons at Antenna Performance Specialties

Regarding tuner upgrades: has anyone dealt with any of the above (or others)?
Whom is considered most recommended for this work?
any opinions are appreciated - thanks, Bob B.

I had Joseph Chow do a tuner mod on a Marantz I had and does a very great and extensive rebuild .He is very cooperative on the phone and enjoys talking to his customers directly which is very refreshing indeed.I posted a Marantz 120 Tuner that I sold on this web site with all of the mod work he did to the unit.I highly recommend him.You will be very happy with the results.
