Ht5r mkii stock tubes

Hey guys I was looking to find out what the stock tubes are in the ht5r mkii units. So I opened mine up to have a look. They are Electro Harmonix in mine. I changed the 12ax7 he to a Tung Sol 12ax7 and it cleaned up the clean channel a bunch. Also the overdrive channel is a bit more crunchy and clear. It didn't help the hum though, she has a good hum on clean or overdrive channel. Hope this answers someone's question. I couldn't find the answer myself.
