Hello, and yes - as near as my ear can tell all the speakers are clear. I also opened up that first cabinet and verified that the cone codes on all the speakers in that one are '010 003'. I'm enlisting the help of a couple friends to double check my ears (just because my ear says they're clear...). ...

One last item worthy of mention... As regards the "series modification" on the normal and brilliant input channels: The way this was done was to have the lower 'brilliant' input jack remain the input for that channel, and to have the upper 'brilliant' input jack be the output of that same ...

Now I suppose it's time for a little bit of a story. I bought this amplifier while I was in the service in Europe over the course of a few months (receipts say 1.8.74, 16.8.74,and 31.1.75). The military shipped it home for me in about June of 1975, and I took it to Michigan and played in clubs with ...

Next speaker cabinet - s/n 4971. AHA! This time I found a cone code that I could photograph, and now that I see what it takes to locate them I found all of them (in this cabinet anyways). I will need to reopen the other cabinet and look again - and I do expect to find them. In this cabinet: NE speak...

first speaker cabinet - s/n 4976. Now, I have looked these over pretty well and I do not see a cone code on any of these 4 speakers ANYWHERE.

a few amplifier internal pictures here... I hope I didn't overdo it.

speaker cabinets to follow.

I do not have those pictures right now... but I knew this question would come up and I'm quite prepared to open it up and get them. Over the course of the next couple days I will do it. I expect I can just post them here (let me know if that's not correct). On a related note: I remember reading a po...

I think I would sell my amp now. I bought this in Frankfurt Germany in 1974. It has been my main gigging amp until about 2 years ago. I'm in Montana (USA), and have decided on $5000 for a price. Anyone interested?

Hi guys! All the advice and suggestion I've gotten here has been spot on, so I'm back with a new question: The 100 watt output can be cut in half by removing 2 of the output tubes, and I've seen it mentioned a few times that removing the 2 outside tubes in the DR103 power tube lineup will accomplsh ...

Thank you gentlemen. I've committed to the exchange, and all the new caps are now in place. I took it to my basement for a test drive, and no flames sprang out when I turned it on. Guitar sounds came out of it and everything! (I still have to run it up for a while - I was gentle out of consideration...

I'm trying not to bother you guys but.... I just committed myself to recapping my early 70s DR103, so I went over to Vintage Hiwatt Restorations and bought a recap kit. I was so busy being concerned about the 16/16, 16/32, 32/32 cap value question that I didn't look very hard at the others, so I end...

Dave, First off - thank you sir for cleaning up after me. I'll try not to be so messy next time. :D As near as I can see, everything you've said is pretty consistent with what I've read thus far. I will do a little experimentation based on what you've offered here. What happened was that I double ch...

Hello, and I'm a brand new addition to this forum (you guys sure have a fun place here). Anyways.... I've been reading everyone's commentary on the different tubes that may be installed in this preamp section - and I've come up with a question. Now - I'm not saying I actually want to do this, but - ...
