ted m	Re: 5E3 Finished - first impressions and a question Howard, the 2nd 8 ohm speaker should be fine, you're presenting a 4 ohm load to the amp but it should be fine, blow a fan in back if it gets hot back there or if it's a hot day and you're plaing a long time. As Bruce and I discovered years ago, many Sovtek 5Y3s especially ones with 4 pins instead of 5, are really putting out 5AR4/GZ34 voltages, and the longevity of a Sovtek is not likely to be as long as a good NOS, which are often < $10, so you might want to be on the lookout for a good US NOS rectifier. If you are going to stick with ~375VDC and 6V6s, I'd highly consider the new JJ 6V6 tubes, they're taller than the EHs and some others by 1/4" or so, but they can easily handle those voltages and last a long time.
