Producentens information om WL-60:
The Amplifon Audio WL-60 is a valve amplifier.
Amplifon Audio web site (June 25, 2009):WL60 amlplifier is practically a developed construction of WL25 with extended output power. By installing a greater power supplier and final level, based on 6550 pentodes, we have achieved 60W of output power. The great power and a wide frequency response with low frequencies, make it possible for the amplifier to operate with the speakers of low effectivity and irregular impendace characteristics.
The final level operates in the ultralinear push-pull system in AB class and can operate with the followin tubes: 6550; KT88; KT90. All the types of tubes given above may be installed without interfering into the amplifier’s construction. WL25 does not require any regulations not only during the exploitation but also during the tube's exchange.
The steering level is based on double 6H2P-EB triode which operates as a pre-amplifier. The steering level and the stage diverter have been built on double 6H6P triode. This type of tube has a great current effectivity and can steer 6550 pentodes of low input impendances with low distortions. The amplifier works with a low 10dB feedback which eliminates all distortions made by the pentodial output system.
