“Can't fault any aspect of transaction”

written by Bordonbert on 30/01/2016

I have used Karltone now twice. The first time was for a pair of 5751 preamp valves and the second for a matched quad of EL84s.

The site is a dream to use, simple and concise with everything available and clear, and with pricing the cheapest around that I can find and transparent. Both times the valves have arrived by lunchtime the very next day despite being purchased late in the afternoon.

All of the valves worked perfectly just as you would expect, but the matching on the quad EL84s is sublime! The pre-matching burn in period for these valves obviously works a treat. I play a Hughes & Kettner Grandmeister 36 which has an active auto-bias feature in it for the output valves. This displays the current matching as flashes in 4 LEDs which you count to show the state of bias of each valve. The aim is to get the number of flashes to match within 4 for each of the two pairs. Even the H&K standard valves were correct to within 3 flashes. The new quad were a perfect match with only one valve having 1 extra flash, and that's superb!

I'll use Karltone again and again and pass my recommendation on to everyone I know as long as service keeps up to this standard.
