1 JimmyR 2 months ago I haven't built an amp for ages because what with our Aussie dollar being worth nothing right now and work being slow I just can't afford it. But I just sold my last 5E3 and a little cash from it so bought a recent DRRI to work on as an alternative to building.A DRRI is a bit of a strange amp for me to buy, because I've never actually liked them! I did gig for a year or two with a Super Reverb RI and remember it as being one of the best amps I have played for getting a good sound out of my Strat. And I have a really, really great Strat and it just doesn't sound very good though my main amp, my home-brew 5F4 1x12 with KT77s. I wanted a small BF amp, or at least something to use with my Strat - as well as my other guitars.Right from the start I was quite surprised by this amp - it actually sounded better than the last one I tried. Still, it was a thinner sound than I wanted and the reverb sounded noisey and boingy. So I have changed a few things already and it's already starting to sound better and better - I'm beginning to really like it.I've swapped out the stock 2-spring reverb pan for a 3-spring pan I happened to have - it's exactly the right size and sounds so much better. I put a .0022µF cap over the 220K resistor to ground at the reverb sockets and it seems to have helped reduce boinginess and noise - I found the mod here: https://robrobinette.com/AB... I also used a 12AY7 for the reverb driver and now the reverb sounds very good.I redid the Vibrato channel tonestack with Sozo blues and silver mica - 250pF, .022µF and .1µF with the stock 100K slope resistor and a 10K treble resistor. So now the tonestack is the same as a SRRI with midrange on full. Clipped the bright cap. Now it sounds so much fuller but still very Fender. Apart from the drag of having to remove every knob to get at the little front panel PCB it's actually been surprisingly easy to work on.And now it has a Celestion G12H in there. It's not necessarily better than the stock Jensen C12K but I'm more used to them. The biggest surprise has been what it sounds like with a Les Paul and the volume on 6 - it's the first time I have ever liked the sound of a breaking-up BF Fender amp. And t has made me want to do the normal channel with an even bigger treble resistor, a 500pF treble cap and two .022µF caps - I think it should roar!This is a "slow and steady" project. If it keeps going this well I have plans to use a bigger power transformer and bigger tubes, so I may end up with a "stealth Deluxe" which is a lot louder than expected. Apparently the standard Mercury Magnetics upgrade power transformer would let me use EL34s... But so far this has been a great experiment. I'm enjoying it far more already than I thought I would. I'll try to remember to take pics next time i'm inside.
