Title: newbie to the Amp building game Post by: Hopeless on May 27, 2008, 01:03:47 AM Hi guys, I've been looking at niks gear for the last 12 months or so. I've decided to go with a JTM45 kit 1 to begin with. I am planning on changing caps to sozos, and will be using a set of trannies I'm trading with a mate for. any tips?
has anyone fitted the Dana Halls VVR2 (powerscaling) to this amp? cheers Mick Title: Re: newbie to the Amp building game Post by: 72fetter on May 28, 2008, 12:06:09 AM just finished a jtm50 with mm trannies....AMAZING!!!!! i recommend you find the jtm 45 instructions pdf on metro amps forum. helped me out bigtime!!!

if i build an amp i would really consider the sozo cap too :) check for PEC (mil spec) pot, these should be good(but really expensive). i would also set some sprague capacitor on the board(bias supplie cap etc) and the preamp a F&T with CarbonComp resistor. and maby set better powertube socket. If you make it this way, please make a clip :), i plant on building something similar soon. the metroamp instruction is something good to get. and with MM trannies your sure it be right. as for the tip, read well around amp building forum, there alot of info :D and take care as there is really high voltage involved into building tubeamp. Title: Re: newbie to the Amp building game Post by: Hopeless on June 02, 2008, 01:24:40 AM yeah it will be a couple of months before I start. I'm getting an unassembled kit 1 and be doing the lot myself. I have orderd a set of Sozo'z already and a vintage style turret board. Already downloaded the Metroamps instructions. ;D
Luckily I have a pro amp builder to help me out step by step. Mick Title: Re: newbie to the Amp building game Post by: Hopeless on June 09, 2008, 05:49:27 AM Has anyone used Marstran trannies in a build? They get a pretty good rap for Marshal style amps
Title: Re: newbie to the Amp building game Post by: bloodedge on June 09, 2008, 11:45:00 AM Has anyone used Marstran trannies in a build? They get a pretty good rap for Marshal style amps yeah, i think some poeple really like the RS(radio spare) replica from marstran, as you said they have good rep. i think the MM are brighter.Title: Re: newbie to the Amp building game Post by: Hopeless on July 24, 2008, 01:04:02 AM Ok I got the kit and have hit a few snags but its steadily being built ;D
Has anyone use a metroamps PT? the wires are confusing me a little. I wired it how My tech said but theres now no lead for the HT fuse ??? Title: Re: newbie to the Amp building game Post by: Roe on July 28, 2008, 06:49:20 PM see the metro amp kit instructions
Title: Re: newbie to the Amp building game Post by: Hopeless on October 11, 2008, 03:22:21 PM Ok so I put it together, I ended up using a metro amps PT and a Mojo (heyboer) O/T. Sozo caps. Shuguang tubes. had a feew misshaps but yesterday I fired it up. Got some nice tones from it in the 2 minutes it was on ;D still a few problems, pretty low output I think ???. has a kind of Rattle in it somewhere, Tubes get DAMNED hot but don't redplate .
has anyone got a voltage chart for these? I have a couple from the JTM45 Yahoo group but I thought if someone has a ceriatone one it might be handy ;) Mick |
