The Quad 306 was designed with the Quad ESL63 in mind, Quad's only speaker at the time, long before the 10L speakers were introduced. In fact, in their brochure Quad recommended the 306 for "the vast majority of domestic systems", adding that the 606 "provides enough power for the largest and most demanding systems". They say "the Quad 306 and 606 use identical circuit designs and the only difference between them is their power output." In 1994 the Quad 306 retailed at £350 inc VAT, the 606 at £690.

Russell's spot on with this one. I bought it to power our 63's at the time- the 10L didn't exist yet. Now I use it to drive our 988's. Installed the dada electronic modifications (new op amp, capacitors, and output connectors). Sounds great.

Pretty sure the 606 would have put the 63's in the arcing and sparking mode.

A good condition Quad 306 and Quad 34 should normally sell for around £150-200 each on Ebay.

all of the transistor gear that quad made was never hyped or advertised particularly hard, especially in the US. Most of it was built for the BBC and recording studios, so it's pro gear. Quad is not really a consumer brand, it's a pro and enthusiast brand, so there's a healthy community of modders and service people. Great stuff to own.
