Powering vtl5c1 from heaters on SLO 100 ?

[djembutz]

I just in progress building Soldano Slo 100 clone. I got my schemo from sloclone forum.
After i almost completed my parts, i realized that my PT do not have 6,3v to powering vtl531 (switching channel). I want powering with 6,3volt from heaters (5Amps).
It's safe ? Or any other method doing that ?
Any help will wellcome..
Thanks

try it, if noisy buy an antek AN-0007 (or AN-0107) and add it for ~$10
