I need your judgment and clarification about these two kinds of resistors that I bought a couple days ago. Actually I bought a pair of Allen Bradley 390K 2W for the output tubes in my Sun Audio amp and want to upgrade to the best quality resistors as AN Tantalum 390K 2W. The seller said that the two resistors look the same but with different quality (I do not want to name the seller at this website but if you know you will be shock!!!). Here are the pictures:
Left one is Allen Bradley and right one is Audio Note Tantalum

Allen Bradley 390K 2W is soldered

Thanks in advance for your clarification.
