Hi Oliver - I just saw the thread: 'Fletcher, have you tried the new Tab-Funkenwerk V-78?'
< for each V module you need a separate +48V ramped circuit (that can be feed from a main supply), sure most V units make it about a year or so without, but as soon as you hear slight crackling, loss of low and/or high end, you have a compromised input x-former. The circuit posted works quite well, is fairly cheap (about $5 in parts) and also takes care of the nasty pop you get if applying +48V. To be precise you need a at least 55V supply so the regulator works properly.
I had several heated arguments with hard core EE that +48V is absolutely save, etc. , but that again everybody send me the broken stuff as soon as it breaks for rewinding and complains about the cost. Take some time for preventive maintenance.... >
Thanks for the info & your ramped phantom circuit diagram,
Question: should it be possible to fit this circuit into an existing V series rack, assuming there's enough physical space?
Thanks again!
