The engineering of vintage equipment was often more sound and reliable than many current items. The only issue is worn out parts and unavailable replacements. Like Philjolet, I own a Sansui amp (AU D-11). My amp and LT-30 have both had substantial upgrades and re-caps. Considering purchase and tech work being around $1000 or less, I'd put them up against equipment far more expensive. The tech I use is Randy Young (Audiogon member "Ezekiel"). He now has more significant upgrades for the LT-30 (owners take note, this is the "next level"). So, be proud of your vintage finds and bring them back to life.
