My dad was a authorized Sylvania dealer for 12 years. I now have his 3748, and LOVE IT. It has a myriad of inputs and even two separate phono inputs with selectable cartridge types. 125W per channel was unheard of back in 1972 and allowed this receiver to stand apart from its competitors. The sound is transparent, true with powerful, tight bass and crystal clear highs. This is what discrete circuitry gets you, vs. cheap op amps. This is a sleeper, and very underrated. If you find one, GRAB IT!!

The RQ 3748 Top Of The Line Receiver sounds as beautiful as it looks once serviced. Made in Batavia NY this quad beast has more than enough juice to get the job done. Hidden gem in the Sylvania lineup if you can actually find one in nice cosmetic condition. Good luck.



re: RQ3748

This amazing Made in the USA receiver is incredible. Hand assembled in Batvia, NY - this competes with any Marantz or Japanese receiver of the day. At 125W/channel, it packs a serious punch, and has the tightest bass I've heard from a receiver of this caliber. It's packed with features and inputs and is a real sleeper in the world of Hi-Fi. I inherited mine from my dad, who was a Sylvania Dealer back in the early 1970s.

This receiver gets 5 stars, and will remain in our family.

I've owned a RQ4748 since 1979. It's still working most excellently. Wondering if it's the same as the 3748. Specs seem the same.

This Receiver is similar to SABA HIFI 8280 Quadro which was sold in Europe
