1970 dr 103 HELP!

Post by MAT76 »

Hi, I recently bought this head.. due to my ignorance (never had played before a pre 73 amp) I found this odd tone stack.... I found the amp unusable. Dark, muddy, muffled sounding... almost impossible to pull something "decent" out of it unless you put Bass at 9' trb 3' mid 10' presence 100% on the upper brill input, all other inputs are unusable (they sound like if you have your guitar tone pot on 1) but this generate some nasty overtones. Please someone have some schematics to mod this amp and take it to a post 73 kind of tone?
May be some of you will tell me not to do it... I'm not a collector and I don't fancy an expensive "ornament" I really need this amp to work.... I'm really disappointed. Please someone help!!

Sounds like there might be other issues.
The one early Fender/Marshall tone stack "one-off" specimen I've heard wouldn't really be described as "dark."

Hopefully Doc or Prof. Huss will chime in... and, yes, "some of us" will tell you not to do it!!!

this amp is an early one with the Fender/Marshall tone stack and cathode follower. A phenomenal amp that just screams when turned up.
a couple guys at the last Convention claimed it was the best sounding DR103 they ever heard.

anyway.

I forwarded a link to Mark's site with layouts and schematics so the amp can be modded to please.

Dude, consider yourself lucky to own one of the early DR103's!

I played a 'standard' '74 DR103 in excellent condition for more than 2 years and when I found a beat up '69/'70 DR103 with this preamp I immediately sold my '74. It's less hi-fi sounding and has a lot more gain and it's the best amp I've ever had! Be sure to put some nice tubes in it and pair it with a cab with Fanes, that's it.

What guitar do you play?

+1.

Don't screw it up. If it's not your sound, sell it and buy something else.

I have a 1970 one with the odd tonestack, but without the cathode follower. It sounds more 'Fenderish'.. a bit less mids than the usual Hiwatts. It's stays clean though, unless you really crank it!
