The DTR-2000 used a single 8877/3CX1500A7 which is much larger
physically than the 8874. I was getting 8877s at the time for $305 (at a
discount)and had a number of them (when the DTR2000 first came out) I
liked the amp, but the voltage regulation was poor and IIRC a bit on the
low side. I had one of the low voltage caps explode. It was loud enough
to make my ears ring. It blew the can right off, which hit the top of
the cabinet. The can looked like a 38 wad cutter that had hit something
really hard.
The MLA2500 used the 8873 (Aluminum anode and transverse cooling) I
believe while the 8874/3CX400 is used in the old alpha 76 and 78 series.
Back then it was much less expensive.Now days you can get 3CX800s for
less although new 8874s and 3CX800s from Eimac are quite pricey.
