Mightiness,
maybe it's just the medication I have to take now, but a question occurred to me: does the preamp in front of the Scryer need gain and if so, how much? On paper, my OB speakers have a sensitivity of 96 dB, but I need to turn up the volume control pretty high in order to get proper, slightly louder than "normal room" volume level.
Thanks in advance.

Mightiness can certainly answer better then I, but with 96dB 1W/1m speakers you'd only need 400mV in to achieve very loud (to most people) listening levels. Most sources can supply this readily. So, to me, your experience seems interesting.
Cheers!
Edited to add - Log taper pots are pretty good at leaving fine adjustment below "noon" to not blow out the ears. With volume "all the way up", does it get loud enough?

Load 8R
400mV in for 2V83 out; all RMS, so 1W@8R; calc sez gain is 7.075V/V, 17db

meaning Scryer is around 7.15V/V gain, means usual sources will give 2Vrms , thus 14.3Vrms out
14.3Vrms@8R=25.56W, just about Scryer in clipping
go figure
conclusion - but I'm finding it general rule - everything is better when having decent preamp (of adequate gain) in chain
have you one?

Thanks for your reply. Yes, it can play loud without issues, I was just curious.Mightiness can certainly answer better then I, but with 96dB 1W/1m speakers you'd only need 400mV in to achieve very loud (to most people) listening levels.

Thanks Mightiness!have you one?![]()
Would you call the Iron Pumpkin "decent"? I would 👍😍

naah.......... that one is boring

How about just work on the Machvs and Bigguv Dickvs amps?

Dose Niamh
that one will be developed for higher range of swing, so more gain and Cojones
so, changing circuit as that to have modest gain ( as needed for Scryer), far from optimal usage
as I see it, every decent Austrian household ought to have ZM's preamp and amp in every room
Hurry now, because in second part of year, I'm going to demand pair of Lederhosen, besides even more Geld!!!

Having a PTSD moment…my German mother used to make me wear them as a child and would take me out in public.
I’m not sure any amount of therapy can fix that…but I’m keeping a hopeful attitude and working towards that goal of having a system in every room that contains ZM designed products.
I wish I had known I could pay in Lederhosen…I would have asked to hold on to them.
if someone is specifically likeable, I can accept (part of!!) payment in Spielhosen ( adequately sized for my Gorgeous Body), instead of Lederhosen
and, important remark, I said - Lederhosen, besides Geld
so hurry, time is near, when I'm going to realize how much I actually need to ask for my Mighty Concoctions

Another one is cooking!
I had parts and PCBs at home for almost a year now, but did not have the time to build it.
The build was straight forward with no problems. My F6 gave its case and PSU for it.
I am looking forward to test my new Scryer! (Hopefully this evening..)
Thanks for all advises in this thread! Thanks ZM!
