Fikk nylig dette svaret fra ARC vedrørende tematikken over:
“ ... we have found that, while some KT150s are not problematic, some KT150 tube sets can cause damage to the VSi60's transformer.
In general, an owner can monitor the temperature of the transformer while using the amp and determine how safe it is to use the KT150s. If the transformer gets too hot to place your hand on the top and leave it there, it is likely to cause damage.
We have used this 'rule of thumb' for years, but of course it is not a guarantee.
So in summary, there are VSi60 owners using KT150s without problems, but it is not our general recommendation.”
Så da får vi se ...
