RG50 TC what were the original tubes ? EL34 or 6L6 ?
« on: March 14, 2016, 12:08:46 PM »
I just bought a used RG50 TC - it has Sovtek 5881 power tubes (same as 6L6 i believe) and i was surprised to see that as all the info on the web says EL34.. Does anyone know for sure what the original valves were ? And if it's been modified, how can i tell if it's been biased correctly ? I know nothing about electronics and i have no testing equipment.. The amp sounds good - i just dont want any melted glass or other problems ! I've only used it for around 40 mins - 1 hour max. in one go and it seems to not heat up too much..
