Default amp relay substitutes

hi, i'm looking for heavier duty relays for LK1AF 5 amp and ALA2F12 3 amp which have same phisical dementions and pin placement that will drop right in place. they are in an onkyo M-282 2 channel power amp rated at 105 wpc. 8 ohm, and 125 wpc. at 6 ohms rms. the ALA2F12, is being used for the speaker relay but, not sure what the LK1AF relays which there are two, are being used for exactley as i have no schematic but, i can feel one of them click when i push the mechanical operated on-off switch which makes and breaks conn. to trans. primary to on then, a red led flashes about 5 times then speaker relay clicks in and, the led then turns yellow. a type of delay circuit i suppose i'm not for sure if its a relay, or delay circuit problem so i thought i'd replace all three of the relays first with something heavier duty since i've doubled the ps capacitance from 10k to 20k per side. rectifiers have been replaced with 30 amp stealth diodes. on-off switch seems to check ok when led goes completly off and i loose sound. any ideas on some heavier duty relays, would be appreaciated thanks, crippledchicken

Thumbs up update on relays!

turns out, i had a bad solder joint on 12v. regulator feeding relays allowing severe voltage fluctuations causing relays to drop out of circuit. problem solved crippledchicken
