90 volt battery eliminator

[tiv48]

hi yorkie. this comes as a ready built modual .changing r1 to 470k gives 70 volt output with a 4.5 volt input see pics of my earlyer post in this thread . i have had it running a vidor 434 for 6 hours ,no hash or other nasties . the first one i tried about 4 years ago was hopeless built arond a 555 and a transformer. thease new ones from ebay Item number: 250747824418 cost only £10.95 +£1.59 postage and as i said before battery pack and modual will fit inside a b126 battery case with plenty of room to spare
the same cant be said for 10 pp3s .i am going to try and use one to make a safe cap reformer next
