I used a very similar RCBS promelt furnace for decades, it worked fine, until about 4 years ago when it just stopped working<br />I looked for replacement parts at the time and was told they were no longer available,<br />I purchased a lyman furnace , as a replacement as it was a bit less cash and held 5 lbs more than the original rcbs,<br />and its working ok, they go on sale occasionally for about $245.<br /><br /><br /><a href="https://www.midwayusa.com/product/1010225661?pid=267665">https://www.midwayusa.com/product/1010225661?pid=267665</a>
