I answer to jmcgrogan2's question and to follow up on Drussheaxe's response:
Current US law dictates that:
mercantile products (cotton) are weighed in Avoirdupois ounces
physical bullion (gold) are weighed in Troy ounces.
Avoirdupois ounce = 28.349 grams
Troy ounce = 31.10 grams
Avoirdupois pound = 16 Avoirdupois ounces
Troy pound = 12 Troy ounces
Avoirdupois pound = 453.504 Avoirdupois grams
Troy pound = 373.2 grams
10 pounds of cotton = 4.53584 Kilograms
10 pounds of gold = 3.732 Kilograms

Thank you very much for that clarification Unsound. You are a gentleman and a scholar! Now, after all these posts we still don't seem to have a quantitative answer to the OP's original question. How many SS watts is 35 tube watts equal to??

Al, Ralph......we are all waiting. Try to be as accurate as Unsound was please. ;^)
^Thank you, but I'm not deserving of it.
A true scholar would have noticed That "I..." should have been "In...", and there is no such thing as "...Avoirdupois grams...".

"...200wpc SET amp..."? What amp might that be?
