For a bit of fun, thought Id investigate the costs involved in getting the kit Id need to bias my own valve power amp.\r\n\r\nFrom the proffessionals Ive spoken to you need an oscilloscope, frequency generator and a multimeter.\r\n\r\nWell, the multimeter Ive got.... thought Id price the rest, so gave RS components a call...\r\n\r\nOscilloscope... from £400 upwards!!! (most around £1k!!)\r\nFrequency generator from £1000 upwards !!!!\r\n\r\n:eek: \r\nthink I might be paying out £35 once every 18 months to a workshop instead, what do you think?? If I bought the kit it should pay for itself in, oh....60 years!! \r\n\r\nUnless Ive missed something?
