Re: Can you jumper the inputs on a Tweedle-Dee?

I built my Tweedle-Dee Deluxe's with 4 inputs. And the other D Deluxe's I'm aware of have 4 inputs. They jumper just fine. :o

Re: Last ODS-50 build

No disrespect to the SSS guy's I spent close to 4 years building prototypes They sound good but not great. When I built the 150 watt amps I could have bought a Marshall Major that's what my builds sounded like. I will be 60 years old next month I don't like heavy weight amps now. I would like to tha...

Re: Last ODS-50 build

Just finished used a old cabinet with a Fane 12L I love this new amp. It makes my SSS amps sound like the oats that have been run through the horse. :)

Re: Last ODS-50 build

Changed V-1 to a mid plate 135k/2k2 x2. V-1 voltages 205/205 V-2 voltages 205/205 I can't ask for any closer voltages than that.
Got rid of the darkness. Now replace the 100pf silver mica with a 500pf silver mica on the bright switch.

Re: Last ODS-50 build

I had to try the Pihers On V-1. I may change to 135k 2k2 135k 2k2 MF7C Mepco Electra 1% Just to balance things out just a little dark on V-1 with the FET input it's perfect The other disappointment is the Marstran 1202-118 PT B+1 421 volts under load played with the dropping string and V-2 207v/207v...

Re: Last ODS-50 build

It's finished everything is adjusted. Had to play with the dropping string a little. It sings the clean channel and the overdrive channel watch out.
I'm happy. :D :D :D

Re: #183 5th Generation ODS Skyliner. Layout/Schematic discussion

Precision power supply is all I use now. I started out with the Axial. Before Jason had board sets we built all our boards from scratch.

Re: #183 5th Generation ODS Skyliner. Layout/Schematic discussion

Just to be clear I used the Heyboer HTS-10359 PT on my #183 build and a Dagnall C1998 OPT from 1968 What I did use a NOS Magic Parts Twin set on was my #102 build it started off with a 1971 Fender Twin set it was 90% when I switched to the Magic parts set it turned my #102 amp into a harmonic genera...

Re: #183 5th Generation ODS Skyliner. Layout/Schematic discussion

Tony, You are correct the Magic Parts are not the same now. The original MP were Thorarsen Meissner EIA code #238
As far as Coax I'm using RG-188 Looks exact but who knows for sure.

Re: Eliminate effects loop ?

Times have changed the effects loop with the Dumbelator is a matched set if nothing else it controls the volume of the amp. Most of the time I use a AC-15 type amp EF-86 volume with a 7 position rotary treble switch and on stage get bitched out if my volume is past 2 to loud. If I want to play any o...

Re: Last ODS-50 build
