The Jadis JA 30 MkII is a French, tube-based pure Class A monoblock power amplifier sold as a matched pair for stereo operation. It uses a push-pull output stage and automatic biasing, with compatibility for KT150 power tubes in the MkII version. Depending on the installed output tubes and configuration, output is commonly specified as 30 W with earlier tube types or up to 45 W pure Class A with KT150 tubes. Each output tube is individually fuse-protected, and the amplifier is designed to deliver substantial low-frequency power, with published specifications extending to 15 Hz under some test conditions. The product is still listed by Jadis and multiple dealers, so it should not be considered definitively discontinued; however, regional availability and exact tube configuration may vary.
