Grant Fidelity Service.....I'd like to know where it is.....I have one of the Psvane TS 845 amps that was bought there and they won't get me a Schematic because I don't have a receipt for the purchase 10 years ago and I'm the third owner......Here is the perfect reason not to buy a Chinese amp from a Canadian dealer..........And I'm sure the same is true when you buy tubes............Chinese tubes from a Canadian dealerĀ
