Which DIY board are you using? If you use the VTA-70 with the stock resistors,I don't care for it. The HF87 has superior iron to the ST70 as far as I see.I haven't removed the output transformer to do a comparative sweep, driven by my wide bandwidth Rotel amp.
I am still floored by the EH 6CA7s that I have that test in the high 8000s.I am very tempted to order another quad of them with the same test numbers to see if they sound as good or maybe I just have a unique quad.

Mike, it's diytube's board.

http://www.diytube.com/phpBB2/viewtopic.php?f=6&t=813

It's the only aftermarket board that has measurements etc in it's instructions. Unfortunately, I believe that it's now out print:(. I'm going to post instructions how to change a KTA70board over to it though. Anyway, it sounds much better than the VTA70 to me but I am going to give the VTA a second shot and i'll do your tweaks to it with a spare st70's and see if I was too hard on it.

  This is the one put out by Ned Carlson right? The VTA uses a much better quality board material than the others.If you have to pull off a part,you don't lift the trace like on some of the others.

    Shannon Parks did it. My VTA board has been though a bit but I think that I can make it work. I have to get some new standoffs though...
