German Phase Linear auto amps are not available for over a decade.  I have Purchased probably the remaining two available new PL amps in  early 2000. 

Home audio Phase Linear was purchased by Pioneer Electronics Corporation in 1979. Pioneer choose to expand the Phase Linear line of components, adding a turntable, cassette deck, equalizers and new speaker designs. Pioneer then sold Phase Linear to Jensen in 1982. Jensen announced its decision to close the Lynnwood plant in December of that year, and production was moved to Texas.

Jensen's involvement with the traditional market niche Phase Linear had carved out for itself was short-lived. The last Phase Linear home and professional stereo component equipment was manufactured in 1983. Jensen moved Phase Linear into auto sound and the brand was discontinued in early 2000.
