JBL L45 Flair (1964–?)
The JBL L45 Flair is an all-transistor stereo receiver introduced in September 1964 as part of JBL's "Flair" line of compact integrated components. JBL's professional studio success led to demand for its systems in the home Audio (1970, p.101). It was the moderately priced junior version of the larger L55 - stripped of some features and using a slightly less powerful amplifier. It was aimed at the apartment dweller or serious listener on a budget, and designed to drive JBL's small L16 and L19 loudspeakers.
The amplifier section is rated at 28 watts per channel with a damping factor of 20:1 at 4-16 ohms and frequency response of ±0.5 dB from 20 Hz to 30 kHz. It's a completely silicon transistorized, DC-coupled Class AB design. Unusually for a receiver of this era, it has a continuously running internal fan for cooling. Owners either appreciated it or found it mildly annoying, since the fan is audible and can be heard changing speed. The front panel keeps tone controls to a minimum to preserve signal-path purity. Bass and treble adjustment lives on a slide switch at the rear. The tuner section uses the same "Riviera" FM circuit as the larger L55. The faceplate is gold-anodized, set in a dark walnut wood case.
Collectors know the L45 Flair for its sound, which is clear, bright, with deep bass, and without the harshness of many early transistor receivers. They also know it for its looks. It is one of the best-looking receivers of its era, with a beautifully lit dial and that wood-and-gold styling.
The practical side is less rosy. The output transistors are long out of production. Substitutes like MJ15003 are commonly used, but the DC-balance circuit is finicky and the bias circuit needs adjustment. The unit runs hot even with the fan, and cracked solder joints on the main PCB are a known failure point. The protection circuit can trip with speakers below 4 ohms. Electrolytic capacitor replacement is recommended after fifty years, particularly the large-value caps in the power supply.
No exact weight, dimensions, original price, FM sensitivity, or THD figures have surfaced in the available documentation. Production run length is also unrecorded. Working examples typically sell for $300-$500 on eBay, reaching $600 with the wood case intact.
