sorted it! seems it was a dodgy (new) main cap, replaced it and now it powers on quick
but staying on the same note!
i have another non working board which doesn't power up (no power LED)
originally i found BU806 was dead (3 legged transistor fitted to metal shield outside of L.O.P.T)
replaced that / no change
when switched off i hear a high pitch wining sound which dies down after a few seconds...
changed all caps
checked the following ok: D901 / IC901 / R901 / R902 / R903 / R904 / R914
