I would prefer that people who are parts dealers not clutter this site with long ads for parts that are readily available and arnt really related to HBR construction. I don't think that is the intent of the site. I occasionally sell parts and tubes on both qth and ebay, but I don't force the group to sift thru my for sale info before getting to the intended content. Thats what those other sites are intended for. I think it's a different story if a individual ham is liquidating his HBR parts inventory, or has a hard to find part such as the special variable cap needed, if transformers , or the Eddystone dial. just my opinion. 73's to all Bill W9VC
