Hey guys,
 
After a lot of deciding between the various tube amps that were suggested to me, I bought an AT-HA5000.
I thought I might as well get an amp to fit the W5k, since my HD650 already sound brilliantly with my Corda Symphony.
The tubes are once again on the back burner.
 
So now I need a voltage converter, so that my UK power line of 240v doesn't fry my newly purchased amp of 100v.
Right?
 
I found the following product:
https://www.amazon.co.uk/US-TRONIC%C2%AE-transformer-appliances-generation-transformers/dp/B01BSVZM52/ref=pd_sim_sbs_23_4?ie=UTF8&dpID=41MsWiIdvoL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&psc=1&refRID=T61N2B2HPXYC4CKNJG86
 
Would that be reasonable?
Or do I need more/less wattage?
 
My budget extends to an absolute max of 100 pounds, or a bit more, if definitely required.
 
Thanks for your help.

Bumping this once just in case the converter I want to buy is going to blow up my house and someone wants to save my life.
Or if someone has any other advice.
