Last ODS-50 build

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.

Nice work. So you went with the Pihers on the plates should be smoooth. My last JTM build I used them throughout and love em!..Let me know how they work out in a Dumble style vs the Metals

Re: Last ODS-50 build
That’s a nice looking build. Well done!
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 V1 201v/200v
It worked out well the power amp is not as loud as my other builds so I can turn it up on stage and not use a dumbelator.
After some burn in time I will put some NOS tubes in it. My PI voltages are lower 259v/266v should make the PI tube last longer.
On the clean channel and overdrive channel it's a harmonic generator infatuate sustain. Last I tried 100pf 200pf on the bright switch will change to 250pf and 500pf.
One more the PAB I used 20m to me it worked better than the 22m just the right level of volume boost.
Time to build a combo cabinet now.
Thank you all, Steve.

Yep! smooth and dark..
If your using ceramics on the stack try replacing them with some micas maybe that will help?

Congrats
Nice looking build
Glad to hear its sounding great

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.

Very nice!

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
Is it just because they don't have the OD?

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 thank all on TAG
