“Last year I built a P1800, which is now back in its original state again. All trials for modifications did kill the perfect sound (e.g. NFB, Sprague caps…) The only modification I kept is on the VCB, which runs perfectly with a 800V Coolmos C3, because I killed the Toshiba chip.
“I run the P1800 at home only in a 2×10“ cabinet equipped with two WGS green beret 25W speakers. I strongly recommend these speakers, for me they sound better than my old Celection G12H 25W from 1965.”
