For EL34 tube integrateds research the Cayin A50T, the Jolida 302 and CJ CAV50. Used prices circa $900, $600 and $1100, respectively. The Cayin is well built, has auto bias and is point to point wired. The Jolida has circut boards but is decently built and servicable. The CJ is long out of production but is well regarded as a classic and still supported by CJ. But I warn you CAV50s come up for sale used infrequently. A used Rogue Cronus is worth checking out but may be a little North of your budget.
For EL34 power amps check out PrimaLuna PL1 and PL2 as well as the Tube Audio Design TAD60. All are excellent for the money. The PL2 will allow for both EL34s and Kt88s, while the PL1 only uses EL34s. Both are auto bias. The TAD is not autobias but is simple to bias. It also can function as a single source integrated. It is out of production but still supported by the internet seller. Used prices for these are generally around $1000, give or take.
All of these mentioned, except the CJ and Rogue, are sourced from China but come through US distribution and are built to quality standards. Given your price point these offer the best value IMHO.
