[RTTY] Need a 924 Titan Guru

Hello to all,
I just replaced the vacuum relay in my 924 Titan and accidently shorted the 28vdc circuit to ground.. When I turned the amp on, it tested the R6 resistor/fuse on the
power supply rectifier board, and damaged several other things.. I replaced R6, diodes D1-D4, and C6.. Still no 28vdc.. Tracked that back to no 20vac from the transformer to the bridge rectifier ?? OH MAN, what did I do ?? Well, I found both circuit board traces from J2 pins 3 and 4 going to the bridge rectifier were open..
Fixed that.. I think the transformer is OK.. Now that you have listened to my story.. Here comes the question.. 

Before I put this all back together, I don’t feel that R6 does the job properly.. What type of fuse could be used to replace R6 ?? It is a 1 ohm 1/2 watt resistor, and there is a space constraint on the circuit board.. Any ideas would help..

A prosperous New Year to all,

‘73    Harry
