ah ok. thanks for answering my question!hi @matttornado , thanks for staying with us!
Sadly Line 'IN' or Return is not something that can really be included in a passive attenuator. All the commercial units that do it are based on active re-amping, where you can deal with line level signals then feed that to an amp. The signals that would be coming in from the effects are far to high impedance and small signal to mix with the low impedance speaker-level signals in a passive attenuator.
Hello Again. I watch this thread from time time after building mine a few years ago when the thread started. I have a Line Out on mine and that works great and was easy to implement. But what If I want a line out Return like an effects loop? How would we bring the LIne Out back in?
Being able to add an effects loop would be the icing on the cake for me. As of now, I use the line out to feed effects then to a second amp.
I can add my plan:ah ok. thanks for answering my question!
Thanks! Any opinions on having a ceramic resistor in the mix?Thanks for the above @JohnH ! That's helpful. I'm in NY, near the CT border. About 2 hrs north of NYC.
So I'll go for the original m2 specs for 4 ohm. I actually figured out how to run my main squeeze 60w amp at 4 ohm as well, so I think this will work for both.
For this build, is there a min. enclosure size you'd recommend? Putting together an order for tomorrow, and I'm hoping to get it right the first time around! I am hoping for one that will be fairly compact to sit on the silvertone when playing out. Looking at the hammond 1550e that Osman used on p 81. (Its 6.732"L X 4.764"W, by 2.169"H) I'm going very pared down (just in, out, 3 switches), so I'm crossing my fingers it will fit. Curious if I should go bigger though.
Also, for one resistor (5.6 ohm 25 watt in R4) I'm having trouble tracking it down without placing a separate order at another supplier, or going to China for long lead times. Do you think a 20 or 25 watt ceramic would work? (I can't post links yet, but there is a rectangular white ceramic style rated at 25W, and a tubular green ceramic style rated at 20W)
Thanks again for all. You and Gene are pretty amazing resources.
Last but not least: @Gene Ballzz I've seen in this thread you were doing some experimenting re: screws, cutting threads into resistors, etc. Have you landed on a favorite method and attending parts?
