Yes, you are right.... I was confused because I thought it said "pi-l" in the
specs sheet. But it doesn't.
Still my question applies to the bigger amplifiers. For example the
specifications of AL-1500 says "pi-l" but if you check the schematics, the
third coil, after C2, called L4 is only tapped once!
