![]() Including various voltages for screen/grid bias etc. But ALSO for Testing numerous Tubes/Circuits, where the 'Heater' varies from 1.2v to 12v, and many DC high voltage outputs from/through 35v, 45v, 78v, 90v, 135v, 200v & higher, for some Tubes. Typically about 1.5v for Tube heaters, and -45v 0 +45v for Anode voltages etc. Firstly, as a replacement for 'Batteries' for some VERY old Valve Radios. I just thought I would explain better about my 'use' of the Power-Supply unit, shown above. The old 'Phono' input will be put to NEW use!!! (Down the track). (And obviously rebuilding it electronically). 6U7G 6J8G 6G8G 6AU6 Y61-or-Y63 6AU6 6J5GT 6V6GT 6V6GT 5Y3GT It WAS part of a Cabinet, including a record player, but I'm not worried about that part!! I'm going to make a nice polished timber escutcheon for the front, and a perspex backing box, that will show off a highly polished metal chassis & top components!! way beyond the original 'look'. It has 10 Tubes, (including a 'Magic-Eye' if wanted). It's a " Hotpoint Bandmaster 19SGZ" which is exactly the same as. It's contagious isn't it!! For anyone interested, I found out about the ' Hotpoint' Chassis. This guy also has boxes & boxes of many hundreds of Valves/Tubes. My ONLY further purchases in the near future, are replacement capacitors & resistors. At the moment, (tonight) I know NOTHING about it!! It is very much on the Back Burner. we found an ancient 'chassis' that may need a new lease on life!! It was a throw-in with the deal, though yet we know NOTHING!!! Be it 'parts' or another unit for restoration? Right now, it is a 'Hotpoint', (seemingly 9 valve?), with 6 ShortWave Bands. when we were going out through the Garage. It won't look like that when I'm finished!!!! DAMN it. Let's not get into the 'Stringing' of the dials!!! (I have all the tech data now, haha.) OK, this guy ALSO had a power-supply, that I wanted as a Battery Replacement for old radios, and although I'll re-build it ENTIRELY inside & out, the majority of the physical construction is now done for me!!!. Switch ( A) moves a rod ( B), swinging arm ( C) that turns the gear ( D) which rotates gear ( E) at 90 degrees and finally operates the waveband switch ( F). Regarding the ABOVE photo, as noted by a repairer. The weirdest thing about the 'mechanics' is this!!. A typical 'Medium' wave from about 200 to 550 Metres, (aprox 1700 to 530 Mhz), And a LONG Wave from about 1100 - 5000 Metres, (about 153 to 279 Khtz). What they call on the dial 'VHF', which is basically 'FM' from about 88 to 100 Mhz. There is NO mains transformer inside!! and It runs on 230/240/250v AC or DC!! It has 3 Bands of operation. SO we also loaded in the car an English Philips Radio, model B3G75U, in pristine condition!!!. ![]() ![]() HOWEVER, while I was there, I was 'Sucked-in' to a few other purchases !!!. It IS in pieces, but every part is there in the box, and the protruding glass band/station piece is in pristine condition! (Although for Aussie Stations!). then WooHoo!!ĭear ' rsjsouza' (and anyone else interested!!! ) Well myself & the 'missus' drove nearly 200kms to Perth, to meet the guy who had the 'Aussie' version of your Philips European BX462A, and did a cheap deal with the 'Aussie' one, '113A' shown here. All gone!! I'm going to rebuild my own, for performing the basics at least, on common tubes. change caps etc, but do NOT bother with voltage measurements until all Tubes/Bases bedded in !! YEARS ago, I had a Tube tester. ![]() How can one do 'voltage' measurements when the cct is non functioning due to the Tube base connections!! YES!. So often, their unchanging oxide coated pins are the initial 'problem'. those old caps need replacing, and some resistors go way high etc., but to me the initial stumbling block is the tubes. It amazes me when 'restorers' (although generally important!), make the VERY last thing they do to check the Valves/Tubes?. I will generally replace all old caps, and were possible make them 'look' old hahaha!. Thank YOU for your offer too, mate!! Yes, even before I've purchased it, I have all the tech info, including the dial-stringing!! Will get back to you when/if I get it & need help! P.S.
