To 129.55.27.4, who changed the transformer information: Transformers do not act as lowpass filters. They block DC voltages. 70V transformers result in a lack of low frequency information. High frequency information is not affected. Revision undone. 74.92.147.125 ( talk) 19:17, 26 March 2008 (UTC)
Is there some independent source that says Crown was the first to come up with those types of amps? I haven't seen it mentioned anywhere else. Tijfo098 ( talk) 23:12, 13 September 2010 (UTC)
The Crown links have died; pasting here if someone wants to salvage the second sentence of the HVTless section:
For example, in 1967, Crown International introduced the DC300 amplifier, which is capable of directly driving 70-volt lines, as well as traditional speaker loads, thanks to its overall power [1] of 500W. [2] In 1987, Crown introduced the Macrotech 2400, capable of driving 100-volt lines directly. [3]

was invoked but never defined (see the
help page).This is just Ohm's law (and Faraday's) and thus rather obvious that putting 3 separate coils in series will add their voltages not counting losses, since this is identical to just having 3 times as many windings of a single coil(according to naive model ignoring again, losses for specific frequencies). The reference itself was broke and I found a new URL for the Tek Notes from that company. https://web.archive.org/web/20070206163808/http://www.audiotransformers.net/tek-notes.htm I'm not able to figure out which specific one mentions stacking them, but I did see notes of 70-volt-output on them. TN-03, seems most relevant. I need someone with more experience to verify if this was the intended set of documents. 47.221.236.73 ( talk) 10:17, 8 June 2020 (UTC) A better question I forgot to mention is rather it was actually done. I can't find a reference to that. :( 47.221.236.73 ( talk) 10:18, 8 June 2020 (UTC)
