Graham's Hi Fi Service
Posted by: mattchup on 31 August 2017
I am looking at acquiring a second hand NAP 300 and 300 PS from a gentleman over here in the states. He said when he came from the UK over to the states in 2013, he had the amp serviced and voltage changed to meet US standards. He said the service from included the capacitors and tants being changed out. He said it was performed at Graham's Hi Fi in London. Is that service they provide? I was on their website but couldn't tell. Thank you!
