Pair of rare PT7 transistors for a CYRUS One Amp pulled from a working amp channel. The other channel was dead and got repaired, but it was eventually decided to change all the power transistors (and drivers). These working Cyrus transistors are now ultra rare, so if someone has a similar problem but want to keep the parts original, here is the chance to get a guaranteed working pair. Postage is for mainland UK only, other buyers please contact me for shipment cost before bidding.
